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. Interacts with CLASP1 and CLASP2. Binds preferentially to tyrosinated microtubules, and only marginally to detyrosinated microtubules. Localizes preferentially to the ends of tyrosinated microtubules. Brain-specific, expressed in the hippocampus, inferior olive, and piriform cortex and in the cerebellum (at protein level).
