Component of the proteinaceous fiber-like linker between two centrioles, required for centrosome cohesion (PubMed:24035387). Is probably involved in the early stages of ciliogenesis (PubMed:30131441, PubMed:39638757). Plays a role in the organization of centriolar satellites, likely by regulating the accumulation of centriolar satellite proteins, such as PCM1 and SSX2IP, at the centrosome (PubMed:30131441). . This is the function of Ensembl gene identifier ENSG00000169683 (LRRC45, leucine rich repeat containing 45).
