We describe PALML, a novel gene encoding a 551 amino acid protein with similarity to paralemmin and the paralemmin-like amino terminal domain of AKAP2, a protein kinase A anchor protein. PALML mRNA is expressed in many tissues and is most abundant in cardiac and skeletal muscle, while absent from brain and blood. Exogenously expressed PALML fusion protein has a widespread cytoplasmic localization, and it is excluded from the nucleus. Human PALML maps on human chromosome 1p21 (between D1S2767 and D1S223). SSCP-HD analysis of exonic sequences in patients with VUR (familial non-syndromic vesicoureteral reflux syndrome) excluded mutations in the PALML gene from causing this disease. PALML, paralemmin and AKAP2 share the presence of a conserved coiled coil region that may mediate protein interactions with shared partners. Based on its resemblance to paralemmin and AKAP2, PALML is hypothesized to be involved in regulating intracellular signaling and membrane-cytoskeletal interactions.
