The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:

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

FunFam 22407: Ras GTPase-activating protein 3

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.

1 Q14644 (/IDA)

There are 16 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 two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.
1 Q14644 (/TAS)
Mitotic cell cycle GO:0000278
Progression through the phases of the mitotic cell cycle, the most common eukaryotic cell cycle, which canonically comprises four successive phases called G1, S, G2, and M and includes replication of the genome and the subsequent segregation of chromosomes into daughter cells. In some variant cell cycles nuclear replication or nuclear division may not be followed by cell division, or G1 and G2 phases may be absent.
1 P48423 (/IMP)
Thrombocyte differentiation GO:0002574
The process in which a relatively unspecialized myeloid precursor cell acquires the specialized features of a thrombocyte, a nucleated cell found in all vertebrates but mammals involved in hemostasis.
1 E7F916 (/IMP)
Sister chromatid cohesion GO:0007062
The cell cycle process in which the sister chromatids of a replicated chromosome become tethered to each other.
1 P48423 (/IMP)
Signal transduction GO:0007165
The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
1 Q14644 (/TAS)
Ras protein signal transduction GO:0007265
A series of molecular signals within the cell that are mediated by a member of the Ras superfamily of proteins switching to a GTP-bound active state.
1 P48423 (/IMP)
Tracheal outgrowth, open tracheal system GO:0007426
The projection of branches of an open tracheal system towards their target tissues. An example of this is found in Drosophila melanogaster.
1 P48423 (/IMP)
Imaginal disc-derived wing morphogenesis GO:0007476
The process in which the anatomical structures of the imaginal disc-derived wing are generated and organized. The wing is an appendage modified for flying.
1 P48423 (/IMP)
Torso signaling pathway GO:0008293
A series of molecular signals initiated by the binding of an extracellular ligand to torso (a receptor tyrosine kinase) on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.
1 P48423 (/NAS)
Anterior/posterior axis specification, embryo GO:0008595
The specification of the anterior/posterior axis of the embryo by the products of genes expressed maternally and genes expressed in the zygote.
1 P48423 (/TAS)
Female meiosis chromosome segregation GO:0016321
The cell cycle process in which genetic material, in the form of chromosomes, is organized and then physically separated and apportioned to two or more sets during the meiotic cell cycle in a female.
