Preferred Label : heterogeneous-nuclear ribonucleoprotein k;
MeSH definition : A heterogeneous-nuclear ribonucleoprotein found in the CELL NUCLEUS and the CYTOPLASM.
Heterogeneous-nuclear ribonucleoprotein K has been implicated in the regulation of
gene expression at nearly all levels: GENETIC TRANSCRIPTION; mRNA processing (RNA
PROCESSING, POST-TRANSCRIPTIONAL), mRNA transport, mRNA stability, and translation
(TRANSLATION, GENETIC). The hnRNP protein has a strong affinity for polypyrimidine-rich
RNA and for single-stranded polypyrimidine-rich DNA. Multiple hnRNP K protein isoforms
exist due to alternative splicing and display different nucleic-acid-binding properties.;
MeSH synonym : hnrnp k; ribonucleoprotein k, heterogeneous-nuclear; heterogeneous nuclear ribonucleoprotein K;
MeSH hyponym : hnRNP K protein; Heterogeneous Nuclear Ribonucleoprotein Particle K Protein; dC-Stretch-Binding Protein; dC Stretch Binding Protein;
