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 Plays an important role in the organization of the cytoskeleton (PubMed:10848969, PubMed:1999398). Binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerization (PubMed:10848969, PubMed:1999398).FUNCTION Potent inhibitor of bone marrow derived stem cell differentiation (PubMed:7694679). Acts by inhibits the entry of hematopoietic pluripotent stem cells into the S-phase (By similarity).SUBUNIT Identified in a complex composed of ACTA1, COBL, GSN AND TMSB4X (PubMed:23009842). Interacts with SERPINB1 (By similarity).INTERACTION Expressed in several hemopoietic cell lines and lymphoid malignant cells. Decreased levels in myeloma cells.INDUCTION By alpha interferons. Decreased levels in THP-1 cells after treatment with recombinant interferon-lambda.PTM AcSDKP is inactivated by ACE, which removes the dipeptide Lys-Pro from its C-terminus.SIMILARITY Belongs to the thymosin beta family.
