Summaries for POC1B Gene

Entrez Gene Summary for POC1B Gene

  • 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. [provided by RefSeq, Oct 2014]

GeneCards Summary for POC1B Gene

POC1B (POC1 Centriolar Protein B) is a Protein Coding gene. Diseases associated with POC1B include Cone-Rod Dystrophy 20 and Retinitis Pigmentosa. An important paralog of this gene is POC1A.

UniProtKB/Swiss-Prot for POC1B Gene

  • Plays an important role in centriole assembly and/or stability and ciliogenesis (PubMed:20008567). Involved in early steps of centriole duplication, as well as in the later steps of centriole length control (PubMed:19109428). Acts in concert with POC1A to ensure centriole integrity and proper mitotic spindle formation. Required for primary cilia formation, ciliary length and also cell proliferation (PubMed:23015594). Required for retinal integrity (PubMed:25044745).

POC1B_HUMAN
  • Cone-rod dystrophy 20 (CORD20) [MIM:615973]: A form of cone-rod dystrophy, an inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa. {ECO:0000269 PubMed:24945461, ECO:0000269 PubMed:25018096, ECO:0000269 PubMed:25044745}. Note=The disease is caused by mutations affecting the gene represented in this entry.
