Nitrogen is incorporated into various metabolites by multifunctional glutamine amidotransferases via reactive ammonia generated by glutaminase hydrolysis of glutamine. Although this process is generally tightly regulated by subsequent synthase activity, little is known about how the glutaminase is inhibited in

The BNIP-2 and Cdc42GAP Homology (BCH) domains constitute a new and expanding family of highly conserved scaffold protein domains that regulate Rho, Ras and MAPK signaling, leading to cell growth, apoptosis, morphogenesis, migration and differentiation. Such versatility is achieved via
