Facts about RAS guanyl-releasing protein 1.
Regulates T-cell/B-cell growth, homeostasis and differentiation by coupling T-lymphocyte/B- lymphocyte antigen receptors to Ras (PubMed:10807788, PubMed:12839994). Regulates NK cell cytotoxicity and ITAM- dependent cytokine production by activation of Ras-mediated ERK and JNK pathways (PubMed:19933860).

Expressed in brain with higher expression in cerebellum, cerebral cortex and amygdala. Expressed in the hematopoietic system. Expressed in T-cells (at protein level). Expressed in NK cells (at protein level) (PubMed:19933860).
Cytoplasm, cytosol. Cell membrane; Peripheral membrane protein. Golgi apparatus membrane; Peripheral membrane protein. Endoplasmic reticulum membrane; Peripheral membrane protein. Found both in the cytosol and associated with membranes. Relocalization to the cell membrane upon activation is F-actin-dependent. Translocates to the Golgi in response to phorbol ester or nerve growth factor. Localizes to somata and dendrites but not to axons of hippocampal pyramidal cells (By similarity).
