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.

comment	FUNCTION Actin-dependent motor protein with a protein kinase activity, playing an essential role in hearing (PubMed:12032315, PubMed:29880844, PubMed:34788109). Probably also plays a role in vision. Required for normal cochlear hair bundle development and hearing. Plays an important role in the early steps of cochlear hair bundle morphogenesis. Influences the number and lengths of stereocilia to be produced and limits the growth of microvilli within the forming auditory hair bundles thereby contributing to the architecture of the hair bundle, including its staircase pattern. Involved in the elongation of actin in stereocilia tips by transporting the actin regulatory factor ESPN to the plus ends of actin filaments (PubMed:29880844, PubMed:34788109).CATALYTIC ACTIVITY L-seryl-[protein] + ATP = O-phospho-L-seryl-[protein] + ADP + H(+)CATALYTIC ACTIVITY L-threonyl-[protein] + ATP = O-phospho-L-threonyl-[protein] + ADP + H(+)CATALYTIC ACTIVITY ATP + H2O = ADP + phosphate + H(+)SUBUNIT Interacts with MORN4 (PubMed:25822849). Interacts (via C-terminus) with ESPN and ESPNL (By similarity).SUBCELLULAR LOCATION Increased localization at the filodium tip seen in the presence of MORN4.ALTERNATIVE PRODUCTS Strongest expression in retina, retinal pigment epithelial cells, cochlea and pancreas.DISEASE The disease is caused by variants affecting the gene represented in this entry.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY In the C-terminal section; belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family.SIMILARITY In the N-terminal section; belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family.
