Webb1 sep. 2024 · Both products of the Ink4a/Arf locus, in addition to being critical cell-cycle regulators, appear to be involved in several disease pathologies. Moreover, the locus’ expression is epigenetically regulated in ES reprogramming processes, thus constituting the ideal candidates to modulate PPCs homeostasis. WebbThe INK4-ARF genes are epigenetically silenced in hematopoietic stem cells but become poised to respond to oncogenic stress as blood cells differentiate. Inactivation of INK4 …
INK4 is a family of cyclin-dependent kinase inhibitors (CKIs). The members of this family (p16 , p15 , p18 , p19 ) are inhibitors of CDK4 (hence their name INhibitors of CDK4), and of CDK6. The other family of CKIs, CIP/KIP proteins are capable of inhibiting all CDKs. Enforced expression of INK4 proteins can lead … Visa mer The INK4a/ARF/INK4b locus encodes three genes (p15INK4b, ARF, and p16INK4a) in a 35-kilobase stretch of the human genome. P15INK4b has a different reading frame that is physically separated from p16INK4a and … Visa mer Polymorphisms of the p15INK4b/p16INK4a homolog were found to segregate with melanoma susceptibility in the Xiphophorus indicating that INK4 proteins have been … Visa mer P16INK4a P16 is formed from four ankyrin repeat (AR) motifs that exhibit a helix-turn-helix conformation except that the first helix in the second AR … Visa mer Initially, it was thought that each INK4 family member was structurally redundant and equally potent. It was later found; however, that INK4 family members are differentially expressed during mouse development. The diversity in expression pattern indicates … Visa mer INK4 proteins are cell-cycle inhibitors.
