Palmdelphin, encoded by PALMD gene, is a newly identified cytosolic isoform of paralemmin-1, a lipid raft-associated protein implicated in cell shape control. Paralemmin (Palm) is a prenyl-palmitoyl anchored membrane protein that can drive membrane and process formation in neurons. Previous finding suggest that palmdelphin may peripherally associate with endomembranes or cytoskeleton-linked structures. Palmdelphin appears to be 80 kDa in Western blotting, larger than the predicated of 63 kDa, and this may be due to the acidic nature of this protein or its posttranslational modification.
