RASGRP4 - RAS guanyl releasing protein 4 Gene
Species: Homo sapiens
About RASGRP4
This gene has 20 transcripts (splice variants), 182 orthologues and 24 paralogues. Biased expression in bone marrow (RPKM 11.0), appendix (RPKM 5.5) and 13 other tissues.
Summary
The protein encoded by this gene is a member of the Ras guanyl nucleotide-releasing protein (RasGRP) family of Ras guanine nucleotide exchange factors. It contains a Ras exchange motif, a diacylglycerol-binding domain, and two calcium-binding EF hands. This protein was shown to activate H-Ras in a cation-dependent manner in vitro. Expression of this protein in myeloid cell lines was found to be correlated with elevated level of activated Ras protein, and the Ras activation can be greatly enhanced by phorbol ester treatment, which suggested a role of this protein in diacylglycerol regulated cell signaling pathways. Studies of a mast cell leukemia cell line expressing substantial amounts of abnormal transcripts of this gene indicated that this gene may play an important role in the final stages of mast cell development. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2009]
