Anti-C22orf32 antibodies enable researchers to detect and measure the C22orf32 antigen in biological samples. This target is a reported synonym of the SMDT1 gene, which encodes single-pass membrane protein with aspartate rich tail 1. This protein is known to be an important regulatory subunit of the mitochondrial calcium uniporter complex (uniplex), a complex that mediates calcium uptake into mitochondria. The human version of C22orf32 has a canonical amino acid length of 107 residues and a protein mass of 11.4 kilodaltons. It is reported to be localized in the mitochondria of cells. C22orf32 is a member of the SMDT1/EMRE protein family.
