The NIPSNAP1 gene is located on chromosome 22 and encodes a protein that consists of 284 amino acids . The protein has a molecular weight of approximately 35.7 kDa . The recombinant form of NIPSNAP1 is often produced in Escherichia coli (E. coli) and includes an N-terminal His-tag for purification purposes .
NIPSNAP1 is primarily localized to the inner mitochondrial membrane, where it may play a role in mitochondrial DNA maintenance . In mice, a similar protein has been shown to inhibit the calcium channel TRPV6 . This suggests that NIPSNAP1 may have a regulatory role in calcium signaling and homeostasis.
