[3][4][5] This gene encodes a calcium-binding protein, which may play a role in the regulation of ion transport.

A similar protein was first described as a potentially important regulatory protein in the dog thyroid and was termed as R2D5 antigen in rabbit.

Alternative splicing of this gene generates two transcript variants.
