Detects endogenous human, mouse and rat CK1δ in Western blots. In Western blots, this antibody does not cross‑react with recombinant human CK1 alpha or rhCK1 gamma ; reactivity with CK1 epsilon is unknown.
Polyclonal Sheep IgG
E. coli-derived recombinant human CK1δ Arg316-Arg415 Accession # P48730
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.

Detection of Human/Mouse/Rat Casein Kinase 1δ by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, K562 human chronic myelogenous leukemia cell line, C2C12 mouse myoblast cell line, NRK rat normal kidney cell line, and Y3-Ag rat myeloid cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat Casein Kinase 1δ Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4568) followed by HRP‑conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Casein Kinase 1δ at approximately 49 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

Background: Casein Kinase 1 delta
Casein Kinase 1 (CK1) represents a group of serine/threonine protein kinases that are present in all eukaryotic organisms. Human CK1 isoforms ( alpha, gamma 1, gamma 2, gamma 3 ,δand epsilon ) act as monomeric constitutively active enzymes that phosphorylate key regulatory proteins involved in the control of cell differentiation, proliferation, chromosome segregation, and circadian rhythms. CK1 family members share a highly conserved kinase domain but differ in their variable N- and C-terminal domains. CK1δ phosphorylates p53 as well as MDM2 and seems to play a principal role in coordinating the effects of these two key regulator proteins on cell growth and genome integrity.
