FunFam 474: Spectrin beta chain

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 4 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Actin binding GO:0003779
Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments.
1 Q00963 (/ISS)
Phosphatidylinositol-4,5-bisphosphate binding GO:0005546
Interacting selectively and non-covalently with phosphatidylinositol-4,5-bisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' and 5' positions.
1 Q00963 (/IDA)
Microtubule binding GO:0008017
Interacting selectively and non-covalently with microtubules, filaments composed of tubulin monomers.
1 Q00963 (/IDA)
Ankyrin binding GO:0030506
Interacting selectively and non-covalently with ankyrin, a 200 kDa cytoskeletal protein that attaches other cytoskeletal proteins to integral membrane proteins.
1 Q00963 (/IDA)

There are 11 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Plasma membrane organization GO:0007009
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the plasma membrane.
1 Q00963 (/TAS)
Negative regulation of microtubule depolymerization GO:0007026
Any process that stops, prevents, or reduces the frequency, rate or extent of microtubule depolymerization; prevention of depolymerization of a microtubule can result from binding by 'capping' at the plus end (e.g. by interaction with another cellular protein of structure) or by exposing microtubules to a stabilizing drug such as taxol.
1 Q00963 (/IMP)
Neuromuscular synaptic transmission GO:0007274
The process of synaptic transmission from a neuron to a muscle, across a synapse.
1 Q00963 (/IMP)
Nervous system development GO:0007399
The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.
1 Q00963 (/IMP)
Axonogenesis GO:0007409
De novo generation of a long process of a neuron, including the terminal branched region. Refers to the morphogenesis or creation of shape or form of the developing axon, which carries efferent (outgoing) action potentials from the cell body towards target cells.
1 Q00963 (/IMP)
Axon guidance GO:0007411
The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.
1 Q00963 (/IMP)
Axon midline choice point recognition GO:0016199
The recognition of molecules at the central nervous system midline choice point by an axon growth cone; this choice point determines whether the growth cone will cross the midline.
1 Q00963 (/IMP)
Long-term strengthening of neuromuscular junction GO:0042062
Any process that results in an increase in the efficacy of transmission at a neuromuscular synapse.
1 Q00963 (/IMP)
Maintenance of presynaptic active zone structure GO:0048790
A process which maintains the organization and the arrangement of proteins at the active zone to ensure the fusion and docking of vesicles and the release of neurotransmitters.
1 Q00963 (/IDA)
Regulation of synapse organization GO:0050807
Any process that modulates the physical form of a synapse, the junction between a neuron and a target (neuron, muscle, or secretory cell).
1 Q00963 (/IMP)
Photoreceptor cell axon guidance GO:0072499
The chemotaxis process that directs the migration of a photoreceptor cell axon growth cone to its target in the optic lobe in response to a combination of attractive and repulsive cues.
1 Q00963 (/IMP)

There are 7 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 Q00963 (/IDA)
Apicolateral plasma membrane GO:0016327
The apical end of the lateral plasma membrane of epithelial cells.
1 Q00963 (/TAS)
Lateral plasma membrane GO:0016328
The portion of the plasma membrane at the lateral side of the cell. In epithelial cells, lateral plasma membranes are on the sides of cells which lie at the interface of adjacent cells.
1 Q00963 (/IDA)
Axon GO:0030424
The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.
1 Q00963 (/IDA)
Neuromuscular junction GO:0031594
The junction between the axon of a motor neuron and a muscle fiber. In response to the arrival of action potentials, the presynaptic button releases molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane of the muscle fiber, leading to a change in post-synaptic potential.
1 Q00963 (/IDA)
Fusome GO:0045169
A large intracellular spectrin-rich structure that has been found in insect germline cells and mammalian hematopoietic cells. The fusome is an elongated, branched structure, formed from the spherical spectrosome organelle.
1 Q00963 (/IDA)
Spectrosome GO:0045170
A germline specific spherical organelle, rich in membrane skeletal proteins. Precursor to the fusome.
