Microtubule-associated formin which regulates both actin and microtubule dynamics. Induces microtubule acetylation and stabilization and actin stress fiber formation (PubMed:18815276). Regulates Golgi ribbon formation (PubMed:26564798). Required for normal cilia assembly. Early in cilia assembly, may assist in the maturation and positioning of the centrosome/basal body, and once cilia assembly has initiated, may also promote cilia elongation by inhibiting disassembly (PubMed:29742020). {ECO:0000269|PubMed:18815276, ECO:0000269|PubMed:26564798, ECO:0000269|PubMed:29742020}. This is the function of Ensembl gene identifier ENSG00000137460 (FHDC1, FH2 domain containing 1).
