RESUMO
A group of salivary-gland-specific proteins, designated gp65, were identified in the mosquito Anopheles albimanus. Two-dimensional gel electrophoresis resolved this group into at least four molecules with pI 6.4-6.5. The N-terminal amino acid sequence was determined for the major species, gp65-1, and degenerate oligonucleotide primers were used to amplify a specific probe for library screening. A 1312 bp cDNA clone encoding a predicted translation product of 386 amino acids was recovered. gp65-1 is expressed abundantly in the medial and distal-lateral lobes of the adult female glands, and is secreted in the saliva. The amino acid sequence has potential sites for N-glycosylation, phosphorylation and myristylation, and is similar to a number of proteins of unknown function from other mosquito species.
