SH3 domain containing ring finger 1

POSH, plenty of SH3s
This gene encodes a protein containing an N-terminus RING-finger, four SH3 domains, and a region implicated in binding of the Rho GTPase Rac. Via the RING-finger, the encoded protein has been shown to function as an ubiquitin-protein ligase involved in protein sorting at the trans-Golgi network. The encoded protein may also act as a scaffold for the c-Jun N-terminal kinase signaling pathway, facilitating the formation of a functional signaling module.

Papers on POSH
Sh3rf2/POSHER protein promotes cell survival by ring-mediated proteasomal degradation of the c-Jun N-terminal kinase scaffold POSH (Plenty of SH3s) protein.
GeneRIF
Greene et al., New York City, United States. In J Biol Chem, 2012
a model in which Sh3rf2 promotes proteasomal degradation of pro-apoptotic POSH in healthy cells and in which apoptotic stimuli lead to rapid loss of Sh3rf2 expression, and consequently to stabilization of POSH and JNK activation and cell death
Possible role of death receptor-mediated apoptosis by the E3 ubiquitin ligases Siah2 and POSH.
GeneRIF
Schwarze et al., Lexington, United States. In Mol Cancer, 2010
The data presented here define POSH and Siah2 as important mediators of death receptor mediated apoptosis and suggest targeting the interaction of these two E3 ligases is a promising novel cancer therapeutic strategy.
POSH promotes cell survival in Drosophila and in human RASF cells.

POSH promotes cell survival in Drosophila and in human rheumatoid arthritis synovial fibroblasts
POSH is involved in Eiger-Basket (TNF-JNK) signaling and embryogenesis in Drosophila.
GeneRIF
Xu et al., Beijing, China. In J Genet Genomics, 2010
evidence that the JNK pathway scaffold protein, POSH, is involved in TNF (Eiger) signaling in Drosophila
Regulation of the protein stability of POSH and MLK family.
GeneRIF
Xu et al., Beijing, China. In Protein Cell, 2010
POSH's ability to induce apoptosis is correlated with its stability as well as its MLK binding ability.
