NCBI Description

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]

Uniprot Description

Function: Functions as a cation- and diacylglycerol (DAG)-regulated nucleotide exchange factor activating Ras through the exchange of bound GDP for GTP. May function in mast cells differentiation. Ref.1 Ref.2 Ref.6 Ref.7

Subcellular location: Cytoplasm. Cell membrane. Note: Recruited to membranes upon activation by DAG. Ref.1 Ref.7

Tissue specificity: Expressed by mast cells and their progenitors (at protein level). Specifically expressed in mononuclear leukocytes. Highly expressed in myeloid cells compared to lymphoid cells. Also detected in heart, skeletal muscle, spleen, liver, placenta and lung. Not detected in brain. Isoform 1 is the major isoform in normal individuals. Isoform 2 is more significantly expressed in a patient with asthma. Isoform 3 is more significantly expressed in a patient with asthma and a mastocytosis patient. Ref.1 Ref.2

Developmental stage: Expressed early during development. Detected in all fetal tissues tested. Ref.1

Domain: The phorbol-ester/DAG-type zinc finger mediates the binding and the functional activation by DAG.

Sequence similarities: Belongs to the RASGRP family.Contains 1 EF-hand domain.Contains 1 N-terminal Ras-GEF domain.Contains 1 phorbol-ester/DAG-type zinc finger.Contains 1 Ras-GEF domain.
