| Abstract |
Plenty of SH3s (POSH) functions as a scaffold protein for the Jun N-terminal kinase (JNK) signal transduction pathway, which leads to cell death in mammalian cultured cells and Drosophila. Here, we show that POSH forms a complex with Apoptosis-linked gene-2 (ALG-2) and ALG-2-interacting protein (ALIX/AIP1) in a calcium-dependent manner. Overexpression of ALG-2 or ALIX in developing imaginal eye discs resulted in roughened or melanized eyes, respectively. These phenotypes were enhanced by co-overexpression of POSH. We found that overexpression of either gene could induce ectopic JNK activation, suggesting that POSH/ALG-2/ALIX may function together in the regulation of the JNK pathway. |
