Battenin is a protein that in humans is encoded by the CLN3gene located on chromosome 16.[5][6] Battenin is not clustered into any Pfam clan, but it is included in the TCDB suggesting that it is a transporter.[7] In humans, it belongs to the atypical SLCs[7][8] due to its structural and phylogenetic similarity to other SLC transporters.
Function
Battenin is involved in lysosomal function. Many alternatively spliced transcript variants have been found for this gene.[6]
Battenin is a transmembrane protein predicted to be composed of 11 transmembrane helices,[8] yet no crystal structure is available.
Clinical significance
Mutations in this gene, as well as other neuronal ceroid-lipofuscinosis (CLN) genes, cause neurodegenerative diseases commonly known as Batten disease, also known as Juvenile Neuronal Ceroid Lipofuscinosis (JNCL) or Juvenile Batten disease.
