Aliases for SIPA1 Gene
External Ids for SIPA1 Gene
The product of this gene is a mitogen induced GTPase activating protein (GAP). It exhibits a specific GAP activity for Ras-related regulatory proteins Rap1 and Rap2, but not for Ran or other small GTPases. This protein may also hamper mitogen-induced cell cycle progression when abnormally or prematurely expressed. It is localized to the perinuclear region. Two alternatively spliced variants encoding the same isoform have been characterized to date. [provided by RefSeq, Jul 2008]
GeneCards Summary for SIPA1 Gene
SIPA1 (Signal-Induced Proliferation-Associated 1) is a Protein Coding gene. Diseases associated with SIPA1 include sporadic breast cancer. Among its related pathways are Ras signaling pathway and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include GTPase activator activity. An important paralog of this gene is SIPA1L2.
