Rabbit anti-Human RASGRP2 Polyclonal Antibody

Uniprot Id

Q7LDG7

Target Species

Human

Target Name

RASGRP2

Target Full Name

RAS guanyl-releasing protein 2

Target Function

Functions as a calcium- and DAG-regulated nucleotide exchange factor specifically activating Rap through the exchange of bound GDP for GTP. May also activates other GTPases such as RRAS, RRAS2, NRAS, KRAS but not HRAS. Functions in aggregation of platelets and adhesion of T-lymphocytes and neutrophils probably through inside-out integrin activation. May function in the muscarinic acetylcholine receptor M1/CHRM1 signaling pathway.

Target Involvement

Bleeding disorder, platelet-type 18 (BDPLT18)

Target Subcellular Location

Cytoplasm, cytosol. Cell membrane; Peripheral membrane protein. Cell junction, synapse, synaptosome. Cell projection, ruffle membrane; Peripheral membrane protein.

Target Protein Families

RASGRP family

Target Tissue Specificity

Detected in platelets, neutrophils and T lymphocytes (at protein level). Expressed in brain where it is enriched in the striatum. Also expressed in the hematopoietic system. Detected in heart, brain, lung, placenta, liver, skeletal muscle and kidney.

Target Background

The protein encoded by this gene is a brain-enriched nucleotide exchanged factor that contains an N-terminal GEF domain, 2 tandem repeats of EF-hand calcium-binding motifs, and a C-terminal diacylglycerol/phorbol ester-binding domain. This protein can activate small GTPases, including RAS and RAP1/RAS3. The nucleotide exchange activity of this protein can be stimulated by calcium and diacylglycerol. Four alternatively spliced transcript variants encoding two different isoforms have been found for this gene.
