" /> heterogeneous-nuclear ribonucleoprotein k - CISMeF





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;

MeSH annotation : see SCR for specific hnRNP entries;

Is substance : O;
