Gene: [01q21/IVL] involucrin;

COM

According to Stroh-1987, the most probable location for IVL is 1q21-22 (the major hybridization signal in q21); however, an additional minor signal site exists, 1p35-36 (where a paralogous sequence is probably located; see GEM:01p3/IVLL)."

GEN

The primary translation product is encoded by the only exon and consists of 585 amino acid residues, 2/3 of which (390 residues that form an internal region) represent a decapeptide repeated 39 times."

EVO

The internal region of IVL (which is a decapeptide repeat) of humans and higher primates substantially differs in length from that of lower primates, although 5'- and 3'-ancestral flanks a very similar in all primates. Thus, IVL represents an example of a gene with specific evolutionary history in higher primates and human."
