CSNK1G1 Protein, Human, Recombinant (His & GST Tag)

Casein kinase I isoform gamma-1, also known as CSNK1G1, is a member of the protein kinase superfamily, CK1 Ser/Thr protein kinase family and casein kinase I subfamily. Thecasein kinase I family of protein kinases are serine / threonine-selective enzymes that function as regulators ofsignal transductionpathways in most eukaryotic cell types. Casein has been used as a substrate since the earliest days of research on protein phosphorylation. Casein kinase activity associated with the endoplasmic reticulum of mammary glands was first characterized in 1974 and its activity was shown to not depend on cyclic AMP. The CKI family of monomeric serine–threonine protein kinases is found in eukaryotic organisms from yeast to human. Mammals have seven family members: alpha, beta 1, gamma 1, gamma 2, gamma 3, delta, and epsilon. The family members have the highest homology in their kinase domains (53%–98% identical) and differ from most other protein kinases by the presence of the sequence S-I-N instead of A-P-E in kinase domain VIII. The CKI family members appear to have similar substrate specificity and substrate selection is thought to be regulated via subcellular localization and docking sites in specific substrates.

A DNA sequence encoding full length of human CSNK1G1 (NP_071331.2) (Met 1-Lys 422) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.

The recombinant human CSNK1G1/GST chimera consists of 659 amino acids and has a calculated molecular mass of 76.3 kDa. It migrates as an approximately 66 kDa band in SDS-PAGE under reducing conditions.

Kinases are highly recommended to be shipped at frozen temperature with blue ice or dry ice. Shipment made at ambient temperature may seriously affect the activity of the ordered products. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
