[[https://www.uniprot.org/uniprot/CDN1B_HUMAN CDN1B_HUMAN]] Defects in CDKN1B are the cause of multiple endocrine neoplasia type 4 (MEN4) [MIM:[https://omim.org/entry/610755 610755]]. Multiple endocrine neoplasia (MEN) syndromes are inherited cancer syndromes of the thyroid. MEN4 is a MEN-like syndrome with a phenotypic overlap of both MEN1 and MEN2.<ref>PMID:17030811</ref>

== Function ==
[[https://www.uniprot.org/uniprot/CDN1B_HUMAN CDN1B_HUMAN]] Important regulator of cell cycle progression. Involved in G1 arrest. Potent inhibitor of cyclin E- and cyclin A-CDK2 complexes. Forms a complex with cyclin type D-CDK4 complexes and is involved in the assembly, stability, and modulation of CCND1-CDK4 complex activation. Acts either as an inhibitor or an activator of cyclin type D-CDK4 complexes depending on its phosphorylation state and/or stoichometry.<ref>PMID:10831586</ref> <ref>PMID:12244301</ref> <ref>PMID:16782892</ref> <ref>PMID:19075005</ref> <ref>PMID:17254966</ref>  [[https://www.uniprot.org/uniprot/SKP1_HUMAN SKP1_HUMAN]] Essential component of the SCF (SKP1-CUL1-F-box protein) ubiquitin ligase complex, which mediates the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription. In the SCF complex, serves as an adapter that links the F-box protein to CUL1. SCF(BTRC) mediates the ubiquitination of NFKBIA at 'Lys-21' and 'Lys-22'; the degradation frees the associated NFKB1-RELA dimer to translocate into the nucleus and to activate transcription. SCF(Cyclin F) directs ubiquitination of CP110.<ref>PMID:16209941</ref> <ref>PMID:20181953</ref> [[https://www.uniprot.org/uniprot/CKS1_HUMAN CKS1_HUMAN]] Binds to the catalytic subunit of the cyclin dependent kinases and is essential for their biological function. [[https://www.uniprot.org/uniprot/SKP2_HUMAN SKP2_HUMAN]] Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins involved in cell cycle progression, signal transduction and transcription. Specifically recognizes phosphorylated CDKN1B/p27kip and is involved in regulation of G1/S transition. Degradation of CDKN1B/p27kip also requires CKS1. Recognizes target proteins ORC1, CDT1, RBL2, MLL, CDK9, RAG2, FOXO1, UBP43, and probably MYC, TOB1 and TAL1. Degradation of TAL1 also requires STUB1. Recognizes CDKN1A in association with CCNE1 or CCNE2 and CDK2. Promotes ubiquitination and destruction of CDH1 in a CK1-Dependent Manner, thereby regulating cell migration.<ref>PMID:12435635</ref> <ref>PMID:11931757</ref> <ref>PMID:12840033</ref> <ref>PMID:12769844</ref> <ref>PMID:15342634</ref> <ref>PMID:16262255</ref> <ref>PMID:15949444</ref> <ref>PMID:16103164</ref> <ref>PMID:15668399</ref> <ref>PMID:16951159</ref> <ref>PMID:16581786</ref> <ref>PMID:17908926</ref> <ref>PMID:17962192</ref> <ref>PMID:22770219</ref>
