title: Amino acid sequence of the precursor of rat liver alpha 2 micro-globulin.
abstract: The amino acid sequence of the signal peptide of the rat liver protein alpha 2 micro-globulin has been determined using a combination of nucleic acid and protein sequencing techniques. The NH2-terminal portion of pre-alpha 2 micro-globulin is: (formula see text) As is the case with most secreted proteins, the majority (13 of 19) of the amino acid residues in this signal are hydrophobic. However, there are no obvious similarities between this signal sequence and that determined for preproalbumin, a protein presumably synthesized and secreted by the same cells in the liver.
