  • Title: Cloning, mapping and tissue-specific expression of Drosophila clathrin-associated protein AP50 gene.
    Author: Zhang YQ, Broadie K.
    Journal: Gene; 1999 Jun 11; 233(1-2):171-9. PubMed ID: 10375633.
    Abstract:
    The Drosophila homologue of AP50, the medium chain of clathrin-associated protein complex AP-2, was identified and characterized from the Drosophila Expressed Sequence Tag database. The Drosophila AP50 is 86% identical to that of mouse and human, and 80% identical to the Caenorhabditis elegans homologue. It is a single-copy gene with two mini-introns in the coding region and it maps to position 94B1-B2 on polytene chromosomes. Two P1 clones, DS01102 and DS0104, were identified that contain the AP50 gene. Alternative 5' UTR splicing is involved in the regulation of AP50 expression. AP50 expression is highly enriched in the central nervous system and midgut caecum during embryo development, and its function is discussed. The two other Drosophila members of the medium-chain family of clathrin-associated protein complexes, AP47 and mu3, have also been identified and mapped to 85D20-D27 and 6E1-E4, respectively.
