AC Q08116; Q07918; DT 01-FEB-1995 (REL. 31, CREATED) DT 01-FEB-1995 (REL. 31, LAST SEQUENCE UPDATE) DT 01-NOV-1997 (REL. 35, LAST ANNOTATION UPDATE) DE REGULATOR OF G-PROTEIN SIGNALING 1 (RGS1) (EARLY RESPONSE PROTEIN DE 1R20) (B-CELL ACTIVATION PROTEIN BL34). GN RGS1 OR 1R20 OR BL34. OS HOMO SAPIENS (HUMAN). OC EUKARYOTA; METAZOA; CHORDATA; VERTEBRATA; TETRAPODA; MAMMALIA; OC EUTHERIA; PRIMATES. RN [1] RP SEQUENCE FROM N.A. RC TISSUE=B-CELL; RX MEDLINE; 94060109. RA NEWTON J.S., DEED R.W., MITCHELL E.L.D., MURPHY J.J., NORTON J.D.; RL BIOCHIM. BIOPHYS. ACTA 1216:314-316(1993). RN [2] RP SEQUENCE FROM N.A. RC TISSUE=B-CELL; RX MEDLINE; 93232596. RA HONG J.X., WILSON G.L., FOX C.H., KEHRL J.H.; RL J. 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: BELONGS TO THE RGS FAMILY.
