RBAF600 associates with RB in the nucleus and with Ca(2+)-bound calmodulin in the cytoplasm.p600 and RB appears to act as a chromatin scaffold, and in the...
UCP1 is activated in the brown fat cell by fatty acids and inhibited by nucleotides. Sympathetic nervous system terminals release Norepinephrine onto a...
UCPs facilitate the transfer of anions from the inner to the outer mitochondrial membrane and the return transfer of protons from the outer to the inner...
UDP-glucose:glycoprotein glucosyltransferase (UGT) is a soluble protein of the endoplasmic reticulum (ER) that selectively reglucosylates unfolded...
UGT-1A is a uridine diphosphate glucuronyltransferase (UDP-glucuronosyltransferase, UDPGT), an enzyme of the glucuronidation pathway that transforms small...
Human cytomegalovirus (CMV) frequently infects young people and persists for the lifetime of the individual in a latent state, due in part to downregulation...
Uromodulin, the most abundant protein in normal urine. Its excretion in urine follows proteolytic cleavage of the ectodomain of its glycosyl...
UNG encodes one of several uracil-DNA glycosylases. One important function of uracil-DNA glycosylases is to prevent mutagenesis by eliminating uracil from...
Uroplakins (UPK) are integral membrane proteins that form 2-dimensional crystalline arrays termed urothelial plaques that cover more than 90% of the apical...
Uqcc, called Bfzb, and identified its human homolog by database analysis. The deduced human and mouse proteins have a single transmembrane domain and share...
UQCRB is a subunit of the respiratory chain protein Ubiquinol Cytochrome c Reductase (UQCR,Complex III or Cytochrome bc1 complex), Subunit 7 was identified...
Catabolism of histidine begins with the conversion of histidine to urocanic acid by histidase (HAL). UROC1, or urocanase (EC 4.2.1.49), catalyzes the second...
Trypsinogen-activation peptide (TAP) is a small peptide that is released when trypsinogen is activated to trypsin. Under physiologic conditions, activation...
Ubiquitin carboxyl-terminal hydrolase 14 is a member of the ubiquitin-specific processing (UBP) family of proteases that is a deubiquitinating enzyme (DUB)...
HAUSPis a ubiquitin specific protease or a deubiquitylating enzyme that cleaves ubiquitin from its substrates.Since ubiquitylation (polyubiquitination) is...
Ubiquitin, a highly conserved protein involved in the regulation of intracellular protein breakdown, cell cycle regulation, and stress response, is released...
Urotensin-II (U-II) is a peptide ligand, initially isolated from the neurosecretory system of the Goby fish (Gillichthys mirabilis) Bern et al. 1969. For...
This gene encodes a protein containing tetratricopeptide repeats which are thought to be involved in protein-protein interactions. This protein is a minor...
UDP-glucuronate decarboxylase (UGD; EC 4.1.1.35) catalyzes the formation of UDP-xylose from UDP-glucuronate. UDP-xylose is then used to initiate...
