kap-1 (F08F8.3, WBGene00002182) notes

Accession choice

• UniProt has two unreviewed entries for kap-1: H2KZP1 (F08F8.3a, 710 aa) and G5EEE6 (F08F8.3b, 713 aa). Q18930 is a different gene, aka-1 (D1022.7, an A-kinase anchor protein); "kap-1" is only a synonym there.
• G5EEE6 was chosen. It is the longer product, and it is the entry that carries the PANTHER IBA rows (PTN000401088) and the ComplexPortal NAS rows, which marks it as the gene-centric representative.
• Not imported, because these GOA rows are on H2KZP1 only: IMP/IGI intraciliary anterograde transport and IGI rows for GO:1902856/GO:1902857 (PMID:17420466, DYF-5 study), plus IDA non-motile cilium (PMID:17420466, PMID:22342749). They are consistent with this review.
• The module (modules/intraflagellar_transport.yaml) names KAP-1 without an accession. G5EEE6 is the recommended one.

Provenance and process

• Deep research: falcon timed out and the perplexity-lite fallback is unavailable. No deep-research file was written.
