The function of MICALL1 (MICAL like 1, ENSG00000100139) is as follows. Lipid-binding protein with higher affinity for phosphatidic acid, a lipid enriched in recycling endosome membranes. On endosome membranes, acts as a downstream effector of Rab proteins recruiting cytosolic proteins to regulate membrane tubulation (PubMed:19864458, PubMed:20801876, PubMed:23596323, PubMed:34100897). Involved in a late step of receptor-mediated endocytosis regulating for instance endocytosed-EGF receptor trafficking (PubMed:21795389). Alternatively, regulates slow endocytic recycling of endocytosed proteins back to the plasma membrane (PubMed:19864458). Also involved in cargo protein delivery to the plasma membrane (PubMed:34100897). Plays a role in ciliogenesis coordination, recruits EHD1 to primary cilium where it is anchored to the centriole through interaction with tubulins (PubMed:31615969). May indirectly play a role in neurite outgrowth (By similarity). {ECO:0000250|UniProtKB:Q8BGT6, ECO:0000269|PubMed:19864458, ECO:0000269|PubMed:20801876, ECO:0000269|PubMed:21795389, ECO:0000269|PubMed:23596323, ECO:0000269|PubMed:31615969, ECO:0000269|PubMed:34100897}.
