Seems to link microtubules to dendritic lamellar body (DLB), a membranous organelle predominantly present in bulbous dendritic appendages of neurons linked by dendrodendritic gap junctions. May operate in the control of brain-specific organelle translocations (By similarity). Interacts with CLASP1 and CLASP2 (PubMed:11290329). Binds preferentially to tyrosinated microtubules, and only marginally to detyrosinated microtubules (PubMed:16954346). Localizes preferentially to the ends of tyrosinated microtubules. Expressed in the brain, and very low levels in kidneys. Expressed at 10.5 dpc, expression declines until birth after which it suddenly increases. Expression gradually decreases until postnatal day 10, (the day when DLBs start to occur), then again increases and reaches the levels present in adult brain.
