Summaries for CERKL Gene

Entrez Gene Summary for CERKL Gene

  • This gene was initially identified as a locus (RP26) associated with an autosomal recessive form of retinitis pigmentosa (arRP) disease. This gene encodes a protein with ceramide kinase-like domains, however, the protein does not phosphorylate ceramide and its target substrate is currently unknown. This protein may be a negative regulator of apoptosis in photoreceptor cells. Mutations in this gene cause a form of retinitis pigmentosa characterized by autosomal recessive cone and rod dystrophy (arCRD). Alternative splicing of this gene results in multiple transcript variants encoding different isoforms and non-coding transcripts.[provided by RefSeq, May 2010]

GeneCards Summary for CERKL Gene

CERKL (Ceramide Kinase Like) is a Protein Coding gene. Diseases associated with CERKL include Retinitis Pigmentosa 26 and Retinitis Pigmentosa. Gene Ontology (GO) annotations related to this gene include NAD+ kinase activity and diacylglycerol kinase activity. An important paralog of this gene is CERK.

UniProtKB/Swiss-Prot for CERKL Gene

  • Has no detectable ceramide-kinase activity. Overexpression of CERKL protects cells from apoptosis in oxidative stress conditions.

  • Retinitis pigmentosa 26 (RP26) [MIM:608380]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. {ECO:0000269 PubMed:14681825, ECO:0000269 PubMed:18978954}. Note=The disease is caused by mutations affecting the gene represented in this entry.
