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 Processive actin-based motor that can move in large steps approximating the 36-nm pseudo-repeat of the actin filament. Can hydrolyze ATP in the presence of actin, which is essential for its function as a motor protein (PubMed:10448864). Involved in melanosome transport. Also mediates the transport of vesicles to the plasma membrane (By similarity). May also be required for some polarization process involved in dendrite formation (By similarity).CATALYTIC ACTIVITY ATP + H2O = ADP + phosphate + H(+)SUBUNIT May be a homodimer, which associates with multiple calmodulin or myosin light chains (By similarity). Interacts with RIPL2, the interaction is required for its role in dendrite formation (By similarity). Interacts with MLPH (PubMed:12062444). Interacts with SYTL4 (By similarity). Interacts with MYRIP (By similarity). Interacts with RAB10; mediates the transport to the plasma membrane of SLC2A4/GLUT4 storage vesicles (PubMed:22908308). Interacts with FMR1; this interaction occurs in association with polyribosome (By similarity).ALTERNATIVE PRODUCTS Detected in melanocytes.DISEASE The disease is caused by variants affecting the gene represented in this entry. Some patients who have MYO5A pathogenic variants and originally diagnosed with Griscelli syndrome 1 may rather have Elejalde syndrome.SIMILARITY Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family.ONLINE INFORMATION MYO5A mutation db
