Previous GeneCards Identifiers for RAP1A Gene
This gene encodes a member of the Ras family of small GTPases. The encoded protein undergoes a change in conformational state and activity, depending on whether it is bound to GTP or GDP. This protein is activated by several types of guanine nucleotide exchange factors (GEFs), and inactivated by two groups of GTPase-activating proteins (GAPs). The activation status of the encoded protein is therefore affected by the balance of intracellular levels of GEFs and GAPs. The encoded protein regulates signaling pathways that affect cell proliferation and adhesion, and may play a role in tumor malignancy. Pseudogenes of this gene have been defined on chromosomes 14 and 17. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]
GeneCards Summary for RAP1A Gene
RAP1A (RAP1A, Member Of RAS Oncogene Family) is a Protein Coding gene. Diseases associated with RAP1A include kabuki syndrome 1 and leukocyte adhesion deficiency, type iii. Among its related pathways are cAMP signaling pathway and Chemokine Signaling. GO annotations related to this gene include GTP binding and protein complex binding. An important paralog of this gene is RAP2B.
UniProtKB/Swiss-Prot for RAP1A Gene
Induces morphological reversion of a cell line transformed by a Ras oncogene. Counteracts the mitogenic function of Ras, at least partly because it can interact with Ras GAPs and RAF in a competitive manner. Together with ITGB1BP1, regulates KRIT1 localization to microtubules and membranes. Plays a role in nerve growth factor (NGF)-induced neurite outgrowth. Plays a role in the regulation of embryonic blood vessel formation. Involved in the establishment of basal endothelial barrier function. May be involved in the regulation of the vascular endothelial growth factor receptor KDR expression at endothelial cell-cell junctions.
