May play a synaptic role at the postsynaptic lipid rafts possibly through interaction with CAMK2A. Interacts with CAMK2A. In neurons, localizes to postsynaptic lipid rafts (By similarity). In myocardial and skeletal muscle cells, localizes to the cytoplasm adjacent to the inner cell membrane, polarized to one end of the myocyte (By similarity). Predominantly expressed in neuroectoderm-derived tissues. Expressed in the brain and spinal cord, and at low levels, in the adrenal gland. In the bone marrow, confined to the CD34+ progenitor cells. Not found in peripheral blood mononuclear cells, nor lymph nodes. Tends to be expressed at high levels in acute myeloid leukemia and glioblastoma cells. Palmitoylation and myristoylation target the protein to the lipid rafts.
