Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Putative serine protease inhibitor.SUBUNIT Interacts with CANX and PDIA3.SUBCELLULAR LOCATION Expressed in the liver, leukocytes and testis. Also detected in brain, colon, uterus, esophagus, spleen, trachea, kidney and lung.DOMAIN The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable (By similarity).PTM Glycosylated.POLYMORPHISM The SERPINA2 gene is highly polymorphic. Deletions, frameshift mutations and a critical start codon variation (ATG->ATA, dbSNP:rs1956172) have been found in some populations. Population studies suggest that a pseudogenization process may be ongoing in humans (PubMed:17135331, PubMed:23826168, PubMed:9383284). 3 potentially functional alleles, V1, V2 and V3, have been described in the literature. The sequence shown in this entry is that of allele V2 (PubMed:23826168).SIMILARITY Belongs to the serpin family.
