===Structure of C-terminal coiled coil of RasGRP1=== | |||

==Disease== | |||
[[http://www.uniprot.org/uniprot/GRP1_HUMAN GRP1_HUMAN]] Disease susceptibility is associated with variations affecting the gene represented in this entry. Aberrantly spliced isoforms and/or diminished levels of RASGRP1 are found in a cohort of SLE patients raising the possibility that dysregulation of this signaling protein contributes to the development of autoimmunity in a subset of SLE patients. | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/GRP1_HUMAN GRP1_HUMAN]] Functions as a diacylglycerol (DAG)-regulated nucleotide exchange factor specifically activating Ras through the exchange of bound GDP for GTP. Activates the Erk/MAP kinase cascade. Couples T-lymphocytes and B-lymphocytes antigen receptors to the activation of Ras. Hence, regulates T-cells and B-cells development, homeostasis and differentiation. Functions also in FcERI-evoked degranulation and cytokine secretion by mast cells, regulating allergic responses. May also function in other cell types differentiation.<ref>PMID:10807788</ref> <ref>PMID:12839994</ref> <ref>PMID:12782630</ref> <ref>PMID:12845332</ref> <ref>PMID:15060167</ref> <ref>PMID:15184873</ref> <ref>PMID:15899849</ref> | |||
