Neogenin (NEO1) is a type I transmembrane protein that is crucial for axonal guidance and neuronal migration. It is also involved in regulating differentiation programs in many embryonic and adult tissues. It is a member of the immunoglobulin (Ig) superfamily and is closely related to deleted in colorectal cancer (DCC). NEO and DCC, together with the UNC5 family of type I transmembrane proteins, are receptors for the netrin/UNC6 family of laminin-related bifunctional guidance molecules that both attract some axons and repel others. In mouse, at least five netrins (netrin‑1, ‑3, -4, G1, and G2) have been identified. Mouse netrin-1 and netrin-3 have been shown to be ligands for mouse NEO. Neogenin protein localizes to nuclear bodies and is thought to associate with chromatin and heterochromatin-associated factors. The protein is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains - a RING, a B-box type 1 and a B-box type 2 - and a coiled-coi

p21WAF1 [DCS-60.2]

p21 / WAF1, also known as cyclin-dependent kinase inhibitor 1 or CDK-interacting protein 1, is a protein that in humans is encoded by the CDKN1A gene located on chromosome 6 (6p21.2). The p21 protein binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at G1. p21 is expressed in all adult human tissues. In tumors, the expression of p21 has been studied by immunohistochemical methods in a wide range of human tumors, such as gastric carcinoma, non-small cell lung carcinoma, and thyroid carcinoma. The expression of p21 is associated with favorable prognosis in various tumors.
