| Primary Identifier | IPR026800 | Type | Family |
| Short Name | DOCK3 |
| description | DOCK family members are evolutionarily conserved guanine nucleotide exchange factors (GEFs) for Rho-family GTPases []. DOCK proteins are required during several cellular processes, such as cell motility and phagocytosis. The N-terminal SH3 domain of the DOCK proteins functions as an inhibitor of GEF, which can be relieved upon its binding to the ELMO1-3 adaptor proteins, after their binding to active RhoG at the plasma membrane [, ]. DOCK family proteins are categorised into four subfamilies based on their sequence homology: DOCK-A subfamily (DOCK1/180, 2, 5), DOCK-B subfamily (DOCK3, 4), DOCK-C subfamily (DOCK6, 7, 8), DOCK-D subfamily (DOCK9, 10, 11) []. This entry represents DOCK3. DOCK3 is linked to Alzheimer disease due to its interaction with presenilin proteins and ability to stimulate Tau/MAPT phosphorylation []. |
