HPCA - hippocalcin Gene
Also Known as BDR2; DYT2
Species: Homo sapiens
About HPCA
This gene has 5 transcripts (splice variants), 202 orthologues, 14 paralogues and is associated with 2 phenotypes. Restricted expression toward brain (RPKM 57.7).
Summary
The protein encoded by this gene is a member of neuron-specific calcium-binding proteins family found in the retina and brain. This protein is associated with the plasma membrane. It has similarities to proteins located in the photoreceptor cells that regulate photosignal transduction in a calcium-sensitive manner. This protein displays recoverin activity and a calcium-dependent inhibition of rhodopsin kinase. It is identical to the rat and mouse hippocalcin proteins and thought to play an important role in neurons of the central nervous system in a number of species. [provided by RefSeq, Jul 2008]
