What does PCNA stand for?
Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication.
What does PCNA stand for in nursing?
1. PCNA. Patient Care Nursing Assistant. Care, Assistant, Nursing.
What is PCNA Gene?
PCNA Gene – Proliferating Cell Nuclear Antigen The protein encoded by this gene is found in the nucleus and is a cofactor of DNA polymerase delta. The encoded protein acts as a homotrimer and helps increase the processivity of leading strand synthesis during DNA replication.
Where is PCNA found?
PCNA (proliferating cell nuclear antigen) has been found in the nuclei of yeast, plant and animal cells that undergo cell division, suggesting a function in cell cycle regulation and/or DNA replication.
Is CNA and Stna the same thing?
STNA stands for State Tested Nursing Assistant. The term is used only in the State of Ohio. Elsewhere nursing assistants are referred to differently: some are called a CNA or Certified Nurse Aide, an LNA or Licensed Nursing Assistant, or simply a NA or Nursing Aide.
What is the function of PCNA?
PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics.
How do proteins interact with PCNA?
Many proteins interact with PCNA via the two known PCNA-interacting motifs PCNA-interacting peptide (PIP) box and AlkB homologue 2 PCNA interacting motif (APIM). Proteins binding to PCNA via the PIP-box are mainly involved in DNA replication whereas proteins binding to PCNA via APIM are mainly important in the context of genotoxic stress.
What is the function of the interdomain connector loop of PCNA?
The interdomain connector loop of human PCNA is involved in a direct interaction with human polymerase delta. The Journal of Biological Chemistry. 1998;273:713–719. [PubMed] [Google Scholar] Articles from Annals of Botanyare provided here courtesy of Oxford University Press
Do plants with two pcnagenes share the same amino acid sequence identity?
In most known cases of plants containing two PCNAgenes, a high level of amino acid sequence identity was observed: A. thaliana, 96·6 %; N. tabacum, 97·0 %; Z. mays, 98·5 %.
