FunFam 443: Spectrin beta, non-erythrocytic 5

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 7 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 Q9NRC6 (/NAS)
Kinesin binding GO:0019894
Interacting selectively and non-covalently and stoichiometrically with kinesin, a member of a superfamily of microtubule-based motor proteins that perform force-generating tasks such as organelle transport and chromosome segregation.
1 Q9NRC6 (/IDA)
Spectrin binding GO:0030507
Interacting selectively and non-covalently with spectrin, a protein that is the major constituent of the erythrocyte cytoskeletal network. It associates with band 4.1 (see band protein) and actin to form the cytoskeletal superstructure of the erythrocyte plasma membrane. It is composed of nonhomologous chains, alpha and beta, which aggregate side-to-side in an antiparallel fashion to form dimers, tetramers, and higher polymers.
1 Q9NRC6 (/IDA)
Myosin tail binding GO:0032029
Interacting selectively and non-covalently with the tail region of a myosin heavy chain.
1 Q9NRC6 (/IDA)
Dynactin binding GO:0034452
Interacting selectively and non-covalently with any part of a dynactin complex; dynactin is a large protein complex that activates dynein-based motor activity.
1 Q9NRC6 (/IDA)
Protein self-association GO:0043621
Interacting selectively and non-covalently with a domain within the same polypeptide.
1 Q9NRC6 (/IDA)
Dynein intermediate chain binding GO:0045505
Interacting selectively and non-covalently with an intermediate chain of the dynein complex.

There are 7 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
MAPK cascade GO:0000165
An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain an additional tiers: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.
1 Q9NRC6 (/TAS)
Endoplasmic reticulum to Golgi vesicle-mediated transport GO:0006888
The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi.
1 Q9NRC6 (/TAS)
Golgi organization GO:0007030
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the Golgi apparatus.
1 Q9NRC6 (/IMP)
Lysosomal transport GO:0007041
The directed movement of substances into, out of or within a lysosome.
1 Q9NRC6 (/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 Q9NRC6 (/TAS)
Actin cytoskeleton organization GO:0030036
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins.
1 Q9NRC6 (/NAS)
Protein homooligomerization GO:0051260
The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.

There are 6 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
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q9NRC6 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 Q9NRC6 (/TAS)
Spectrin GO:0008091
Membrane associated dimeric protein (240 and 220 kDa) of erythrocytes. Forms a complex with ankyrin, actin and probably other components of the membrane cytoskeleton, so that there is a mesh of proteins underlying the plasma membrane, potentially restricting the lateral mobility of integral proteins.
1 Q9NRC6 (/NAS)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
1 Q9NRC6 (/NAS)
Photoreceptor connecting cilium GO:0032391
The portion of the photoreceptor cell cilium linking the photoreceptor inner and outer segments. It's considered to be equivalent to the ciliary transition zone.
1 Q9NRC6 (/IDA)
Photoreceptor disc membrane GO:0097381
Stack of disc membranes located inside a photoreceptor outer segment, and containing densely packed molecules of photoreceptor proteins that traverse the lipid bilayer. Disc membranes arise as evaginations of the ciliary membrane during the development of the outer segment and may or may not remain contiguous with the ciliary membrane.
