The protein encoded by this gene contains an ATS1/RCC1-like domain, a RhoGEF domain, and a vacuolar protein sorting 9 (VPS9) domain, all of which are guanine-nucleotide exchange factors that activate members of the Ras superfamily of GTPases. The protein functions as a guanine nucleotide exchange factor for the small GTPase RAB5. The protein localizes with RAB5 on early endosomal compartments, and functions as a modulator for endosomal dynamics. Mutations in this gene result in several forms of juvenile lateral sclerosis and infantile-onset ascending spastic paralysis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]
GeneCards Summary for ALS2 Gene
ALS2 (Alsin Rho Guanine Nucleotide Exchange Factor ALS2) is a Protein Coding gene. Diseases associated with ALS2 include Primary Lateral Sclerosis, Juvenile and Spastic Paralysis, Infantile-Onset Ascending. Among its related pathways are Amyotrophic lateral sclerosis (ALS) and RAB GEFs exchange GTP for GDP on RABs. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and Rab GTPase binding. An important paralog of this gene is HERC1.
