OX NCBI_TaxID=9606; RN [1] RP SEQUENCE FROM N.A.

Immunol. 150:3895-3904(1993). CC -!- FUNCTION: INHIBITS SIGNAL TRANSDUCTION BY INCREASING THE GTPASE CC ACTIVITY OF G PROTEIN ALPHA SUBUNITS THEREBY DRIVING THEM INTO CC THEIR INACTIVE GDP-BOUND FORM. THIS PROTEIN MAY BE INVOLVED IN THE CC REGULATION OF B-CELL ACTIVATION AND PROLIFERATION. CC -!- TISSUE SPECIFICITY: B-CELL SPECIFIC. EXPRESSION IS RELATIVELY LOW CC IN B CELLS AND CHRONIC LYMPHOCYTIC LEUKEMIA B CELLS; HOWEVER, IN CC OTHER TYPES OF MALIGNANT B CELL SUCH AS NON-HODGKIN'S LYMPHOMA AND CC HAIRY CELL LEUKEMIA, EXPRESSION IS CONSTITUTIVELY HIGH. CC -!- INDUCTION: IN RESPONSE TO SEVERAL B-CELL ACTIVATION SIGNALS. CC -!- PTM: COULD BE PHOSPHORYLATED. MIGHT BE FUNCTIONALLY REGULATED BY CC PROTEIN KINASE(S). CC -!- SIMILARITY: CONTAINS 1 RGS DOMAIN.
