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 Involved in sperm flagellum axonemal organization and function (PubMed:12223483, PubMed:32161152). May regulate cilium motility through its role in the assembly of the axonemal radial spokes (By similarity).SUBUNIT Interacts with MYCBP and AKAP1 (PubMed:12223483). Part of a complex containing MYCBP, AKAP1 and PRKAR2B. Interacts with CFAP61 (By similarity). Interacts with CFAP70 (By similarity).SUBUNIT Does not interact with MYCBP.INTERACTION Localized in the neck of the sperm.SUBCELLULAR LOCATION Additional isoforms may exist.TISSUE SPECIFICITY Strongly expressed in the liver.TISSUE SPECIFICITY Widely expressed, but strongly expressed in all spermatogenesis-related tissues, including the testis, the epithelium of cauda and the corpus epididymis, as well as the spermatid and mature sperm. Also expressed in Leydig cells.PTM Phosphorylated by PKA.DISEASE The disease is caused by variants affecting the gene represented in this entry.MISCELLANEOUS May be produced by alternative promoter usage.SIMILARITY Belongs to the CFAP91 family.SEQUENCE CAUTION Truncated N-terminus.
