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 a fundamental role in microtubule organizing center structure and function. Required for centriole duplication and correct spindle formation. Has a role in regulating cytokinesis and genome stability via cooperation with CALM1 and CCP110.FUNCTION Involved in global genome nucleotide excision repair (GG-NER) by acting as component of the XPC complex. Cooperatively with RAD23B appears to stabilize XPC. In vitro, stimulates DNA binding of the XPC:RAD23B dimer.FUNCTION The XPC complex is proposed to represent the first factor bound at the sites of DNA damage and together with other core recognition factors, XPA, RPA and the TFIIH complex, is part of the pre-incision (or initial recognition) complex. The XPC complex recognizes a wide spectrum of damaged DNA characterized by distortions of the DNA helix such as single-stranded loops, mismatched bubbles or single-stranded overhangs. The orientation of XPC complex binding appears to be crucial for inducing a productive NER. XPC complex is proposed to recognize and to interact with unpaired bases on the undamaged DNA strand which is followed by recruitment of the TFIIH complex and subsequent scanning for lesions in the opposite strand in a 5'-to-3' direction by the NER machinery. Cyclobutane pyrimidine dimers (CPDs) which are formed upon UV-induced DNA damage esacpe detection by the XPC complex due to a low degree of structural perurbation. Instead they are detected by the UV-DDB complex which in turn recruits and cooperates with the XPC complex in the respective DNA repair.FUNCTION As a component of the TREX-2 complex, involved in the export of mRNAs to the cytoplasm through the nuclear pores.SUBUNIT Monomer. Homooligomer (PubMed:15356003). Interacts with SFI1 (PubMed:16956364). Interacts with CCP110 (PubMed:16760425). Component of the XPC complex composed of XPC, RAD23B and CETN2 (PubMed:11279143, PubMed:15964821, PubMed:16533048, PubMed:16627479). Component of the nuclear pore complex (NPC)-associated TREX-2 complex (transcription and export complex 2), composed of at least GANP, 2 copies of ENY2, PCID2, SEM1/DSS1, and either centrin CETN2 or centrin CETN3. The TREX-2 complex also associates with ALYREF/ALY and with the nucleoporin NUP153 (PubMed:22307388, PubMed:23591820). Interacts with USP49 (PubMed:36702832). Forms a microtubule-associated complex with POC5, POC1B and FAM161A (PubMed:32110738). Interacts with CCDC15 (PubMed:37934472).INTERACTION Localizes to the inner scaffold in the central region of centrioles and to the distal end of centrioles.MISCELLANEOUS Binds two moles of calcium per mole of protein.SIMILARITY Belongs to the centrin family.
