Popis: | We isolated a cDNA encoding the pig oocyte zona pellucida protein ZP3 alpha from a pig ovary lambda gt11 cDNA library. The 1699 bp cDNA contains a short 3' untranslated region characteristic of cDNAs encoding zona proteins. The deduced amino acid sequence for ZP3 alpha consists of 536 amino acid residues and shares 66% overall identity with a 55 kDa rabbit zona protein. Important features of the ZP3 alpha polypeptide include a predicted N-terminal signal sequence, twenty-two cysteine residues, an O-glycosylated domain and potential attachment sites for five N-linked sugar chains. A multibasic tetrapeptide occurs upstream of a predicted C-terminal transmembrane sequence; this suggests proteolytic processing of an integral membrane precursor within the constitutive secretory pathway. |
