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. Multiple alternatively spliced transcript variants have been found for this gene, but the full-length nature of some variants has not been defined. [provided by RefSeq, Jul 2008]

NCBI Reference Sequences (RefSeq)

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.

  1. NM_004706.4NP_004697.2  rho guanine nucleotide exchange factor 1 isoform 2

    See identical proteins and their annotated locations for NP_004697.2

    Status: REVIEWED

    Description
    Transcript Variant: This variant (2) has an alternate 5' exon and uses a downstream start codon, as compared to variant 1. The encoded isoform 2 thus has a shorter N-terminus, as compared to isoform 1.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (3) has an alternate 5' exon and lacks an in-frame internal exon, as compared to variant 1. The encoded isoform 3 thus has a shorter N-terminus and lacks an internal segment, as compared to isoform 1.
