Summary: This gene encodes a protein that sorts transmembrane proteins into lysosomes/vacuoles via the multivesicular body (MVB) pathway. This protein, along with other soluble coiled-coil containing proteins, forms part of the ESCRT-III protein complex that binds to the endosomal membrane and recruits additional cofactors for protein sorting into the MVB. This protein may also co-immunoprecipitate with a member of the IFG-binding protein superfamily. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the upstream ring finger protein 103 (RNF103) gene. [provided by RefSeq, Nov 2010]

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.

See identical proteins and their annotated locations for NP_001005753.1

Status: REVIEWED

Description

Transcript Variant: This variant (2) lacks an alternate exon in the 5' coding region, compared to variant 1. This results in translation initiation from a downstream start codon and an isoform (2, also known as Vps24beta) that has a shorter N-terminus, compared to isoform 1.

Status: REVIEWED

Description

Transcript Variant: This variant (4) lack two internal exons in the 5' region, compared to variant 1. This variant is represented as non-coding because it lacks a significant portion of the coding region, as found in variant 1. Translation from the upstream start codon, as found in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
