Description
Purified anti-p63 (ΔN). Reactivity: Human (recognizes δN-isoforms). p63 (ΔN) is a member of the p53 family. This protein has multiple isoforms TA p63-α, -β, γ, ΔN p63-α, -β, and -γ. The molecular weights of the p63 isoforms α=66 kD, β=52 kD, and γ=45 kD. This nuclear protein is essential for limb formation, epidermal morphogenesis, and epithelial stem cell regeneration. ΔN isoforms are antagonistic to p53; TA isoforms can transactivate p53 targets. The p63 ΔN isoforms repress TA isoforms; mutant p53 abrogates p63 transactivation. This protein interacts with p53, p73, and the various TA- and ΔN isoforms. The Poly6190 antibody recognizes human p63 ΔN isoforms and has been shown to be useful for Western blotting.
