Also known as: GEF; Lfc; P40; GEFH1; LFP40; GEF-H1; NEDMHM
Summary: Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein coupled receptors. The encoded protein may form complex with G proteins and stimulate rho-dependent signals. Alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Jun 2009]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Description

Transcript Variant: This variant (4) contains an alternate 5' exon, resulting in a distinct 5' UTR, use of a downstream start codon, and uses two alternate in-frame splice sites in the 5' and 3' coding regions, compared to variant 1. The resulting isoform (4) has a shorter N-terminus, and contains an internal segment compared to isoform 1. Variants 4 and 5 encode the same protein (isoform 4).
