p21 Cip1 (alternatively p21 Waf1), also known as cyclin-dependent kinase inhibitor 1 or CDK-interacting protein 1, is a cyclin-dependent kinase inhibitor (CKI) that is capable of inhibiting all cyclin/CDK complexes, [5] though is primarily associated with inhibition of CDK2.
In Hermann–Mauguin notation, space groups are named by a symbol combining the point group identifier with the uppercase letters describing the lattice type.Translations within the lattice in the form of screw axes and glide planes are also noted, giving a complete crystallographic space group.
The discovery of the first CKIs in yeast and P21 in mammals has led to research on family of molecules. [8] Further research has demonstrates that Cdks, cyclins and CKIs play essential roles in processes such as transcription, epigenetic regulation, metabolism, stem cell self-renewal, neuronal functions and spermatogenesis.

Platform 21 (Latvian: Platforma 21, P21, also stylized as p 21) [3], previously known as For Each and Every One (Latvian: Katram un katrai, KuK) and Law and Order (Likums un kārtība, LuK), is a right-wing populist political party in Latvia. [4]
p21 activated kinases (PAKs) are members of a family of enzymes. [1] They serve as targets for the small GTP binding proteins CDC42 and Rac and have been implicated in a wide range of biological activities. Members include: PAK1, regulating cell motility and morphology [2] PAK2, possibly playing a role in apoptosis [3]
RAS p21 protein activator 1 or RasGAP (Ras GTPase activating protein), also known as RASA1, is a 120-kDa cytosolic human protein that provides two principal activities: Inactivation of Ras from its active GTP -bound form to its inactive GDP -bound form by enhancing the endogenous GTPase activity of Ras, via its C-terminal GAP domain

GTPase HRas, from "Harvey Rat sarcoma virus", also known as transforming protein p21 is an enzyme that in humans is encoded by the HRAS gene. [ 5 ] [ 6 ] The HRAS gene is located on the short (p) arm of chromosome 11 at position 15.5, from base pair 522,241 to base pair 525,549. [ 7 ]
