Deletion of histidine triad nucleotide-binding protein 1/PKC-interacting protein in mice enhances cell growth and carcinogenesis.
PKC-interacting protein (PKCI), also designated histidine triad nucleotide-binding protein 1, belongs to the histidine triad (HIT) family of proteins. Its structure is highly conserved from bacteria to humans and shares homology with the tumor-suppressor gene fragile histidine triad (FHIT). Although it was originally thought to inhibit PKC, its actual physiologic function is not known. Therefor...
متن کاملKinetic mechanism of human histidine triad nucleotide binding protein 1.
Human histidine triad nucleotide binding protein 1 (hHint1) is a member of a ubiquitous and ancient branch of the histidine triad protein superfamily. hHint1 is a homodimeric protein that catalyzes the hydrolysis of model substrates, phosphoramidate and acyl adenylate, with a high efficiency. Recently, catalytically inactive hHint1 has been identified as the cause of inherited peripheral neurop...
متن کاملStructural characterization of human histidine triad nucleotide-binding protein 2, a member of the histidine triad superfamily.
The histidine triad proteins (HITs) constitute a large and ubiquitous superfamily of nucleotide hydrolases. The human histidine triad nucleotide-binding proteins (hHints) are a distinct class of HITs noted for their acyl-AMP hydrolase and phosphoramidase activity. The first high-resolution crystal structures of hHint2 with and without bound AMP are described. The differences between hHint2 and ...
متن کاملThe histidine triad superfamily of nucleotide-binding proteins.
Histidine triad (HIT) proteins were until recently a superfamily of proteins that shared only sequence motifs. Crystal structures of nucleotide-bound forms of histidine triad nucleotide-binding protein (Hint) demonstrated that the conserved residues in HIT proteins are responsible for their distinctive, dimeric, 10-stranded half-barrel structures that form two identical purine nucleotide-bindin...
متن کاملNutritional stress exacerbates hepatic steatosis induced by deletion of the histidine nucleotide-binding (Hint2) mitochondrial protein.
The histidine nucleotide-binding protein, Hint2, is a mitochondrial phosphoramidase expressed in liver, brown fat, pancreas, and muscle. The livers of Hint2 knockout (Hint2(-/-)) mice accumulate triglycerides and show a pattern of mitochondrial protein lysine hyperacetylation. The extent and nature of the lysine acetylation changes and the response of Hint2(-/-) mice to nutritional challenges t...
