Gene: RCN2 (reticulocalbin 2) Homo sapiens
Symbol: RCN2
Name: reticulocalbin 2
Description: The protein encoded by this gene is a calcium-binding protein located in the lumen of the ER. The protein contains six conserved regions with similarity to a high affinity Ca(+2)-binding motif, the EF-hand. This gene maps to the same region as type 4 Bardet-Biedl syndrome, suggesting a possible causative role for this gene in the disorder. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2012]
Type: protein-coding
RefSeq Status: REVIEWED
