AP17 and AP19 are the smallest polypeptide chain components of AP-2 and AP-1, the clathrin-associated protein complexes found in coated structures of the plasma membrane and Golgi apparatus of mammalian cells. cDNA clones representing the entire coding sequence of AP17 and AP19 were isolated from rat and mouse brain cDNA libraries, respectively. Determination of their nucleotide sequence predicts proteins of 142 and 158 amino acids with Mr 17,018 and 18,733. A sequence comparison of rat brain AP17 with mouse brain AP19 demonstrates that the small chains are highly related. A computer search for other related proteins has uncovered in yeast a previously unknown gene whose DNA sequence encodes a protein homologous to the small chain of AP complexes. The yeast sequence predicts Yap17p, a protein with 147 amino acids and a Mr of 17,373 that is slightly more related to the mammalian AP17 chain than to its AP19 counterpart.
