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:
"Rho GTPase activation protein
".
FunFam 270:
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 6 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 |

|
G-protein alpha-subunit binding GO:0001965
Interacting selectively and non-covalently with a G-protein alpha subunit. The alpha subunit binds a guanine nucleotide.
|
1 | Q54L90 (/IPI) |
|
Ras GTPase binding GO:0017016
Interacting selectively and non-covalently with any member of the Ras superfamily of monomeric GTPases.

1 | Q54L90 (/IMP) |
|
Cytoskeletal rearrangement involved in phagocytosis, engulfment GO:0060097
The assembly, arrangement, or disassembly of cytoskeletal structures that is involved in the internalization of bacteria, immune complexes and other particulate matter or of an apoptotic cell by phagocytosis.
|
1 | Q54L90 (/IMP) |
|
Regulation of positive chemotaxis to cAMP GO:0061118
Any process that modulates the rate, frequency, or extent of directed movement of a motile cell or organism up a concentration gradient of 3',5'-cAMP.
|
1 | Q54L90 (/IMP) |
|
Negative regulation of protein serine/threonine kinase activity GO:0071901
Any process that decreases the rate, frequency, or extent of protein serine/threonine kinase activity.
