RGH PROTEINS -
RHG proteins possess a 12 amino acid RHG motif. This motif, also known as the IAP-binding motif (IBM), interacts with the BIR domain of Inhibitor of apoptosis proteins (IAPs) and relieving IAP-mediated caspase inhibition. Over-expression of individual RHG proteins is sufficient to induce apoptosis. (Adapted from FBrf0225510).

Additional Descriptive Data
skl expression is induced in pole cells by maternal Tao, but full induction is suppressed in nos+ pole cells.
skl transcripts are first detected at embryonic stage 11, in a pair of symmetric pair of cell clusters in the dorsal anterior region of the head. By stage 12, a second symmetric pair of skl-positive cell clusters appear on the ventral anterior region of the head. Additionally, skl-positive cell clusters are present in the neurogenic region. Clusters of skl-positive cells are observed in the embryonic brain and ventral nerve cord for the rest of embryogenesis. The overall pattern is similar to that of cells that are expected to die in the nervous system.

    Additional comments
    Source for merge of skl BcDNA:RE14076 was a shared cDNA ( date:030728 ).
    Other Comments
    The presence of skl in the Skp complex suggests that, like morgue, it may target th for degradation by the SCF complex.
    skl may be an IAP antagonist and a transducer of apoptotic damage signalling.
    skl may act with other IAP-inhibitory proteins to regulate apoptosis during development.
