The function of Ensembl gene identifier ENSG00000100629 (CEP128, centrosomal protein 128) is as follows. Is involved in the negative regulation of ciliogenesis and plays a role in spermatogenesis (PubMed:29514088, PubMed:35296684). Contributes to the regulation of the TGFB/BMP signaling pathway at the primary cilium, where it is required for ciliary localization of RAB11A, likely affecting the trafficking and regulation of TGFB/BMP pathway components (PubMed:29514088). Required, together with ODF2, for the formation of the subdistal appendage of the centriole (By similarity). {ECO:0000250|UniProtKB:Q8BI22, ECO:0000269|PubMed:29514088, ECO:0000269|PubMed:35296684}.
