The protein is a component of actin-containing microfilaments, and it is involved in the control of cell shape, adhesion, and contraction. Polymorphisms in this gene are associated with a susceptibility to pancreatic cancer type 1, and also with a risk for myocardial infarction. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]
The HRPT2 gene product, parafibromin, is a tumor suppressor protein that is part of the human Paf1 complex. The yeast counterpart to this complex is part of the RNA polymerase II complex as well, and is important for histone modification and connections to posttranscriptional events. Human parafibromin also associates with the RNA polymerase II large subunit.
Human Immunodeficiency Virus (HIV) and Simian Immunodeficiency Virus (SIV) require coreceptors to enter and infect target cells. They are dependent upon an interaction between the viral envelope glycoprotein with T cell antigen T4 (CD4) and a G protein coupled receptor (GPCR). HIV1 infection relies upon interaction with a chemokine receptor, usually chemokine (C-C) receptor 5 (CCR5). During progression of the infection, the virus tends to rely upon chemokine (C-X-C) receptor 4 (CXCR4). SIV a
This gene encodes an essential enzyme of nucleotide metabolism. The encoded protein forms a ubiquitous, homotetrameric enzyme that hydrolyzes dUTP to dUMP and pyrophosphate. This reaction serves two cellular purposes: providing a precursor (dUMP) for the synthesis of thymine nucleotides needed for DNA replication, and limiting intracellular pools of dUTP. Elevated levels of dUTP lead to increased incorporation of uracil into DNA, which induces extensive excision repair mediated by uracil glyc
