CC   -!- FUNCTION: Involved in G1 arrest. May mediate TGF beta-induced G1
CC       arrest. Binds to and inhibits complexes formed by cyclin E-CDK2,
CC       cyclin A-CDK2, and cyclin D1-CDK4. Interaction with nucleoporin
CC       NUP50 is required for nuclear import and for degradation of
CC       phosphorylated p27Kip1 after nuclear import (By similarity).
CC   -!- SUBUNIT: Interacts with NUP50 and with UHMK1. Interacts with COPS5
CC       subunit of COP9 signalosome complex, leading to its subsequent
CC       degradation (By similarity).
CC   -!- INTERACTION:

CC       P61981:YWHAG; NbExp=1; IntAct=EBI-519280, EBI-359832;
CC   -!- SUBCELLULAR LOCATION: Nuclear and cytoplasmic in quiescent cells.
CC       Upon cell cycle progression, mostly cytoplasmic (By similarity).
CC   -!- TISSUE SPECIFICITY: Expressed in all tissues tested. Highest
CC       levels in skeletal muscle, lowest in liver and kidney.
CC   -!- DOMAIN: A peptide sequence containing only AA 28-79 retains
CC       substantial KIP1 cyclin A/CDK2 inhibitory activity.
CC   -!- PTM: Phosphorylation on Ser-10 leads to nuclear export to the
CC       cytoplasm and promotes cell cycle progression (By similarity).
CC   -!- SIMILARITY: Belongs to the CDI family.
