Summary: POC1 proteins contain an N-terminal WD40 domain and a C-terminal coiled coil domain and are part of centrosomes. They play an important role in basal body and cilia formation. This gene encodes one of the two POC1 proteins found in humans. Mutation in this gene result in autosomal-recessive cone-rod dystrophy. Alternative splicing results in multiple transcript variants.

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.

NR_037659.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks an internal exon in the 5' region, but includes an additional exon in the central region, compared to variant 1. This variant is represented as non-coding because the use of the supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).

AK027829, AK295596, AW149266, BU521431, DC354425
NR_037660.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (4) uses alternate exon structure in the 5' region, compared to variant 1. This variant is represented as non-coding due to the presence of multiple upstream ORFs that are expected to inhibit translation of the longest ORF; translation of an upstream ORF would render the transcript a candidate for nonsense-mediated mRNA decay (NMD).
