UniProtKB - Q2NKQ1 (SGSM1_HUMAN)
Protein
Small G protein signaling modulator 1
Gene
SGSM1
Organism
Homo sapiens (Human)
Status
Functioni
Interacts with numerous Rab family members, functioning as Rab effector for some, and as GTPase activator for others. Promotes GTP hydrolysis by RAB34 and RAB36. Probably functions as GTPase effector with RAB9A and RAB9B; does not stimulate GTP hydrolysis with RAB9A and RAB9B.1 Publication
