Enables calmodulin binding activity and microtubule binding activity. Acts upstream of or within N-terminal peptidyl-L-cysteine N-palmitoylation and negative regulation of microtubule depolymerization. Located in Golgi-associated vesicle and cis-Golgi network. Orthologous to human MAP6D1 (MAP6 domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
