RABBIT ANTI hnRNP K

Rabbit anti Human hnRNP K antibody recognizes the heterogeneous nuclear ribonucleoprotein K, also known as dC-stretch binding protein and transformation upregulated nuclear protein.

The hnRNP K protein belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. Encoded by the HNRNPK gene, hnRNP K is located in the nucleoplasm and has three repeats of KH domains that binds to RNAs. It is distinct among other hnRNP proteins in its binding preference; it binds tenaciously to poly(C). This protein is also thought to have a role during cell cycle progession. Several alternatively spliced transcript variants have been described for HNRNPK, however, not all of them are fully characterized (provided by RefSeq, Jul 2008).

Rabbit anti Human hnRNP K antibody detects a band of 62 kDa. The antibody has been extensively validated for western blotting using whole cell lysates.
