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 Required to promote assembly of the transition zone in primary cilia. Acts by specifically recognizing and binding the axonemal microtubule. Localizes to the distal ends of centrioles before ciliogenesis and directly binds to axonemal microtubule, thereby promoting and restricting transition zone formation specifically at the cilia base. Required to mediate CEP290 association with microtubules.SUBUNIT Interacts with CEP290 (PubMed:23644468). Interacts with CPNE4 (By similarity). Interacts with alpha-tubulin (By similarity).INTERACTION Localizes to the distal end of centrioles throughout the cell cycle. During ciliogenesis, found at the cilia base. Localizes to spindle microtubules during mitosis.ALTERNATIVE PRODUCTS Promotes ectopic assembly of transition zone components at cilia tips when targeted outside distal ends of centrioles, generating extra-long cilia with strikingly swollen tips.SIMILARITY Belongs to the CEP162 family.CAUTION Was initially thought to regulate chromosome segregation and mitotic spindle assembly (PubMed:16302001). However, it was later shown that its absence neither affect mitosis nor centriole duplication (PubMed:23644468).SEQUENCE CAUTION Truncated N-terminus.
