CATH Superfamily 2.30.29.30

Pleckstrin-homology domain (PH domain)/Phosphotyrosine-binding domain (PTB)

The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Pleckstrin-homology domain (PH domain)/Phosphotyrosine-binding domain (PTB)
".

FunFam 445: ephexin-1 isoform X2

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 1 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
Rho guanyl-nucleotide exchange factor activity GO:0005089
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
 2 Q9VVC6 (/ISS) Q9Y150 (/ISS)

There are 4 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
Imaginal disc-derived leg morphogenesis GO:0007480
The process in which the anatomical structures of a leg derived from an imaginal disc are generated and organized. A leg is a limb on which an animal walks and stands. An example of this is found in Drosophila melanogaster.
 2 Q9VVC6 (/IMP) Q9Y150 (/IMP)
Melanotic encapsulation of foreign target GO:0035011
Formation of a multilayered, melanized sheath of cells around a foreign invader.
 2 Q9VVC6 (/IMP) Q9Y150 (/IMP)
Positive regulation of Rho protein signal transduction GO:0035025
Any process that activates or increases the frequency, rate or extent of Rho protein signal transduction.
 2 Q9VVC6 (/ISS) Q9Y150 (/ISS)
Regulation of neurotransmitter secretion GO:0046928
Any process that modulates the frequency, rate or extent of the regulated release of a neurotransmitter from a cell.
 2 Q9VVC6 (/IGI) Q9Y150 (/IGI)

There are 1 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
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.
