CC -!- FUNCTION: May be involved in p53/TP53 mediated inhibition of cellular CC proliferation in response to DNA damage. Binds to and inhibits cyclin- CC dependent kinase activity, preventing phosphorylation of critical CC cyclin-dependent kinase substrates and blocking cell cycle progression. CC Functions in the nuclear localization and assembly of cyclin D-CDK4 CC complex and promotes its kinase activity towards RB1. At higher CC stoichiometric ratios, inhibits the kinase activity of the cyclin D- CC CDK4 complex (PubMed:25329316). Inhibits DNA synthesis by DNA CC polymerase delta by competing with POLD3 for PCNA binding (By CC similarity). Plays an important role in controlling cell cycle CC progression and DNA damage-induced G2 arrest (By similarity). CC {ECO:0000250|UniProtKB:P38936, ECO:0000269|PubMed:25329316}. CC -!- FUNCTION: Plays an important role in controlling cell cycle progression CC and DNA damage-induced G2 arrest (PubMed:37178686). Involved in CC p53/TP53 mediated inhibition of cellular proliferation in response to CC DNA damage. Also involved in p53-independent DNA damage-induced G2 CC arrest mediated by CREB3L1 in astrocytes and osteoblasts CC (PubMed:37178686). Binds to and inhibits cyclin-dependent kinase CC activity, preventing phosphorylation of critical cyclin-dependent CC kinase substrates and blocking cell cycle progression. Functions in the CC nuclear localization and assembly of cyclin D-CDK4 complex and promotes CC its kinase activity towards RB1. At higher stoichiometric ratios, CC inhibits the kinase activity of the cyclin D-CDK4 complex CC (PubMed:25329316). Inhibits DNA synthesis by DNA polymerase delta by CC competing with POLD3 for PCNA binding (By similarity). CC {ECO:0000250|UniProtKB:P38936, ECO:0000269|PubMed:25329316, CC ECO:0000269|PubMed:37178686}. CC -!- SUBUNIT: Interacts with HDAC1; the interaction is prevented by CC competitive binding of C10orf90/FATS to HDAC1 facilitating acetylation CC and protein stabilization of CDKN1A/p21 (PubMed:20154723). Interacts CC with MKRN1. Interacts with PSMA3. Interacts with PCNA. Component of the CC ternary complex, cyclin D-CDK4-CDKN1A. Interacts (via its N-terminal CC domain) with CDK4; the interaction promotes the assembly of the cyclin CC D-CDK4 complex, its nuclear translocation and promotes the cyclin D- CC dependent enzyme activity of CDK4. Binding to CDK2 leads to CDK2/cyclin CC E inactivation at the G1-S phase DNA damage checkpoint, thereby CC arresting cells at the G1-S transition during DNA repair. Interacts CC with PIM1 (By similarity). Interacts with STK11 (PubMed:25329316). CC Interacts with NUAK1 (By similarity). Interacts with DTL and TRIM39 (By CC similarity). {ECO:0000250|UniProtKB:P38936, CC ECO:0000269|PubMed:20154723, ECO:0000269|PubMed:25329316}. CC -!- INTERACTION: CC P39689; Q9Z111: Gadd45g; NbExp=2; IntAct=EBI-1174103, EBI-1173616; CC P39689; P17918: Pcna; NbExp=2; IntAct=EBI-1174103, EBI-1173716; CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P38936}. Nucleus CC {ECO:0000269|PubMed:20154723}. CC -!- INDUCTION: By p53, mezerein (antileukemic compound) and interferon CC beta. CC -!- DOMAIN: The C-terminal is required for nuclear localization of the CC cyclin D-CDK4 complex. {ECO:0000250}. CC -!- DOMAIN: The PIP-box K+4 motif mediates both the interaction with PCNA CC and the recruitment of the DCX(DTL) complex: while the PIP-box CC interacts with PCNA, the presence of the K+4 submotif, recruits the CC DCX(DTL) complex, leading to its ubiquitination. {ECO:0000250}. CC -!- PTM: Phosphorylation of Thr-140 or Ser-141 impairs binding to PCNA. CC Phosphorylation at Ser-112 by GSK3-beta enhances ubiquitination by the CC DCX(DTL) complex (By similarity). Phosphorylation of Thr-140 by PIM2 CC enhances its stability and inhibits cell proliferation. Phosphorylation CC of Thr-140 by PIM1 results in the relocation of CDKN1A to the cytoplasm CC and enhanced CDKN1A protein stability. UV radiation-induced CC phosphorylation at Ser-78 and Ser-141 by NUAK1 leads to its CC degradation. {ECO:0000250|UniProtKB:P38936, CC ECO:0000269|PubMed:25329316}. CC -!- PTM: Ubiquitinated by MKRN1; leading to polyubiquitination and 26S CC proteasome-dependent degradation. Ubiquitinated by the DCX(DTL) CC complex, also named CRL4(CDT2) complex, leading to its degradation CC during S phase or following UV irradiation. Ubiquitination by the CC DCX(DTL) complex is essential to control replication licensing and is CC PCNA-dependent: interacts with PCNA via its PIP-box, while the presence CC of the containing the 'K+4' motif in the PIP box, recruit the DCX(DTL) CC complex, leading to its degradation. Ubiquitination at Ser-2 leads to CC degradation by the proteasome pathway. Ubiquitinated by RNF114; leading CC to proteasomal degradation (By similarity). CC {ECO:0000250|UniProtKB:P38936}. CC -!- PTM: Acetylation leads to protein stability. Acetylated in vitro on CC Lys-136, Lys-149, Lys-156 and Lys-158. Deacetylation by HDAC1 is CC prevented by competitive binding of C10orf90/FATS to HDAC1. CC {ECO:0000269|PubMed:20154723}. CC -!- SIMILARITY: Belongs to the CDI family. {ECO:0000305}.
