Product Overview

Description	Recombinant Human Ribonuclease K6 is produced by our Mammalian expression system and the target gene encoding Trp24-Leu150 is expressed with a 6His tag at the C-terminus.
Accession	Q93091
Synonym	Ribonuclease K6; RNase K6; RNASE6; RNS6
Gene Background	Ribonuclease K6 (RNASE6) is a secreted protein that belongs to the pancreatic ribonuclease family. Human RNASE6 is synthesized as a 150 amino acid precursor that contains a 23 amino acid signal sequence, and a 127 amino acid mature chain. RNASE6 is expressed in many tissues, with high expression levels in the lung, with lower expression levels in the heart, placenta, kidney, pancreas, liver, brain, and skeletal muscle. It is also detected in monocytes and neutrophils. RNASE6 may have a role in host defense.

Target Details

Target Function	Ribonuclease which shows a preference for the pyrimidines uridine and cytosine. Has potent antibacterial activity against a range of Gram-positive and Gram-negative bacteria, including P.aeruginosa, A.baumanii, M.luteus, S.aureus, E.faecalis, E.faecium, S.saprophyticus and E.coli. Causes loss of bacterial membrane integrity, and also promotes agglutination of Gram-negative bacteria. Probably contributes to urinary tract sterility. Bactericidal activity is independent of RNase activity.
Subcellular Location	Secreted. Lysosome. Cytoplasmic granule.
Protein Families	Pancreatic ribonuclease family
Database References	HGNC: 10048 OMIM: 601981 KEGG: hsa:6039 STRING: 9606.ENSP00000302046 UniGene: Hs.23262
Tissue Specificity	Highly expressed in spleen (at protein level). Has little or no expression in healthy kidneys (at protein level). Detected in interstitial leukocytes in infected kidneys (at protein level). Expressed in ureter where it localizes to urothelial and submucos

Gene Functions References

These results indicate that RNase6, as previously reported for RNase3, is able to specifically agglutinate Gram-negative bacteria as a main trait of its antimicrobial activity. PMID: 27089320

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
