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 Component of the nexin-dynein regulatory complex (N-DRC), a key regulator of ciliary/flagellar motility which maintains the alignment and integrity of the distal axoneme and regulates microtubule sliding in motile axonemes (By similarity). Plays a critical role in the assembly of N-DRC and also stabilizes the assembly of multiple inner dynein arms and radial spokes. Coassembles with DRC1 to form a central scaffold needed for assembly of the N-DRC and its attachment to the outer doublet microtubules (PubMed:24094744).SUBUNIT Component of the nexin-dynein regulatory complex (N-DRC). Interacts with DRC1 (PubMed:34169321).SUBCELLULAR LOCATION Highly expressed in adult testis, in spermatocytes and spermatids. Also observed in spermatogonia. Not detected in Leydig cells, nor in fetal testis (at protein level).DISEASE The disease is caused by variants affecting the gene represented in this entry. Cilia ultrastructure show normal outer dynein arms, radial spokes and central pairs, but a reduction in inner dynein arms and nexin links. In 5%-15% of cilia, microtubules are disorganized. Nasal epithelial cilia reveal a stiff, dyskinetic cilia waveform.SIMILARITY Belongs to the DRC2 family.SEQUENCE CAUTION Truncated N-terminus.
