CLN3 regulates endosomal function by modulating Rab7A

Mutations in CLN3 are a cause of juvenile neuronal ceroid lipofuscinosis (JNCL),also known as Batten disease.Clinical manifestations include cognitive regression,progressive loss of vision and motor function,epileptic seizures and a significantly reduced lifespan.CLN3 localizes to endosomes and lysosomes,and has been implicated in intracellular trafficking and autophagy.A yeast model for the study of Batten disease PNASAlthough the CLN3 gene for Batten disease,the most common inherited neurovisceral storage disease of childhood,was identified in 1995,the function of the corresponding protein still remains elusive.We previously cloned the Saccharomyces cerevisiae homologue to the human CLN3 gene,designated BTN1 ,which is not essential and whose product is 39% identical and 59% similar to Cln3p.12345NextThe E295K DNA polymerase beta gastric cancer-associated The E295K DNA polymerase beta gastric cancer-associated variant interferes with base excision repair and induces cellular transformation.[Tieming Lang,Shibani Dalal,Anna Chikova,Daniel DiMaio,Joann B Sweasy] PMID 17526740
