Summary: This gene encodes a member of the CHMP/Chmp family of proteins which are involved in multivesicular body sorting of proteins to the interiors of lysosomes. The initial prediction of the protein sequence encoded by this gene suggested that the encoded protein was a metallopeptidase. The nomenclature has been updated recently to reflect the correct biological function of this encoded protein. Several transcripts encoding different isoforms have been found for this gene.

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.

NM_001083314.4 → NP_001076783.1 charged multivesicular body protein 1a isoform 1

Status: REVIEWED

Description

Transcript Variant: This variant (1) lacks an alternate exon in the 5' coding region that results in a frameshift in subsequent regions of the CDS, compared to variant 2. The encoded isoform (1) shares the first two residues but is otherwise distinct and longer than isoform 2. Translation of this isoform is assumed due to use of the expected start codon, which has a strong Kozak signal.

NR_046418.3 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) uses an alternate splice site in the 3' region, compared to variant 2. This variant is represented as non-coding because use of the supported start codon, as used in variant 2, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
