Plays a role as an effector of the ADP-ribosylation factor-like protein 2, ARL2. Detected in the midbody matrix. Not detected in the Golgi, nucleus and on the mitotic spindle. Centrosome-associated throughout the cell cycle. Not detected to interphase microtubules. The complex formed with ARL2BP, ARL2 and SLC25A4 is expressed in mitochondria (By similarity). Belongs to the ARL2BP family. It is uncertain whether Met-1 or Met-4 is the initiator. Truncated N-terminus. Truncated N-terminus.
