Listed are ELISA Kits for the detection of KAL4, an alias name of prokineticin 2. The human protein, encoded by the gene PROK2, is 129 amino acid residues long and has a mass of 14,314 daltons. However, there are up to 2 reported isoforms. It is a member of the AVIT (prokineticin) family. This protein is reported to have a secreted cellular localization. The gene is associated with Hypogonadotropic hypogonadism 4 with or without anosmia. This target may also be known as: protein Bv8 homolog, BV8, HH4, KAL4, and BV8.
