Crebtide (KRREILSRRPSYR) is a substrate peptide derived from the protein Creb which is widely utilized as a synthetic substrate for the PKA and PKC kinase families. This affinity purified rabbit polyclonal anti-pCrebtide antibody is developed with phosphorylated Crebtide (KRREILSRRPpSYR) and absorbed with non-phosphorylated Crebtide.

p33 (ING1) is a new growth inhibitor candidate for a tumour suppressor gene. p33 (ING1) cooperates with p53 and down-regulates cell growth by activating transcription from the p21/WAF1 promoter although there is no sequence similarity between p33 (ING1) and p53.
