Usage
For Research Use Only. Not for use in diagnostic or therapeutic procedures.
Plays an important role in centriole assembly and/or stability and ciliogenesis. Involved in early steps of centriole duplication, as well as in the later steps of centriole length control. 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. Required for retinal integrity.
Gene References into Functions
Depletion of CEP295 blocks the incorporation of POC5 and POC1B into the distal portion of centrioles and suppresses the post-translational modification of centriolar microtubules . Our study thus uncovers a new role for CEP295 during centriole elongation. PMID: 27185865
Intronic SNP in POC1B/GALNT4 locus (rs11105306) was associated with NT-proBNP levels in patients with acute coronary syndrome (ACS). The POC1B/GALNT4 SNP was not associated with higher risk of cardiovascular death. PMID: 26908625
Study found that homozygous POC1B mutation, i.e., c.737C --> T(p.T246 M), cosegregated with the phenotype of a tested family, indicating that POC1B gene was the most possible pathogenic gene for paroxysmal kinesigenic dyskinesia PMID: 26650803
Study indicates that POC1B is required for retinal integrity, and is proposed POC1B mutations as a probable cause for Joubert syndrome with severe polycystic kidney disease. PMID: 25044745
POC1B is a novel gene for a new disease typical of cone-rod dystrophy except that patients did not report night blindness. PMID: 24945461
POC1B mutations result in a defect of the photoreceptor sensory cilium and thus affect cone and rod photoreceptors. PMID: 25018096
Poc1A and Poc1B play redundant, but essential, roles in generation of stable centrioles, but Poc1B may have additional independent functions during cell cycle progression. PMID: 23015594

Poc1B is required for primary ciliogenesis; Poc1 provides a molecular link between the assembly and stability of centrioles for ciliary-based motility in T. thermophila and cilia formation and function in zebrafish and humans PMID: 20008567
Based on these data, we propose that Pix1 and Pix2 are microtubule-associated adaptor proteins that likely contribute to a range of developmental and cell division processes. PMID: 18068700
