Enables identical protein binding activity; microtubule binding activity; and phosphoprotein binding activity. Involved in several processes, including cortical microtubule organization; establishment of planar polarity; and inner ear development. Acts upstream of or within several processes, including cytoskeleton organization; nervous system development; and transport along microtubule. Located in several cellular components, including centrosome; perinuclear region of cytoplasm; and stereocilium. Part of microtubule associated complex. Is expressed in several structures, including alimentary system; early conceptus; genitourinary system; nervous system; and sensory organ. Used to study Miller-Dieker lissencephaly syndrome and lissencephaly. Human ortholog(s) of this gene implicated in lissencephaly and lissencephaly 1. Orthologous to human PAFAH1B1 (platelet activating factor acetylhydrolase 1b regulatory subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
