There are a number of ELISA Kits available for the measurement of YLR066W, another term for the human protein, signal peptidase complex subunit 3. Other synonyms may include: SPase 22 kDa subunit, SPase 22/23 kDa subunit, microsomal signal peptidase 22/23 kDa subunit, microsomal signal peptidase 23 kDa subunit, PRO3567, SPC22/23, and YLR066W. It is encoded by the SPCS3 gene to yield a protein 180 amino acids in length and 20.3 kDa in size. The protein, an enzyme, is categorized into the SPCS3 family. Versions of YLR066W are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
