== Function ==
[https://www.uniprot.org/uniprot/PMYT1_HUMAN PMYT1_HUMAN] Acts as a negative regulator of entry into mitosis (G2 to M transition) by phosphorylation of the CDK1 kinase specifically when CDK1 is complexed to cyclins. Mediates phosphorylation of CDK1 predominantly on 'Thr-14'. Also involved in Golgi fragmentation. May be involved in phosphorylation of CDK1 on 'Tyr-15' to a lesser degree, however tyrosine kinase activity is unclear and may be indirect. May be a downstream target of Notch signaling pathway during eye development.<ref>PMID:9001210</ref> <ref>PMID:10373560</ref>

== Publication Abstract from PubMed ==
CCNE1 amplification occurs in breast cancer and currently lacks effective therapies. PKMYT1 as a synthetic lethal target for CCNE1 amplification holds promise for the treatment of CCNE1-amplified breast cancer. Herein, we discover a series of 2-amino-[1,1'-biphenyl]-3-carboxamide derivatives as potent and selective PKMYT1 inhibitors using structure-based drug design. The representative compound 8ma exhibited excellent potency against PKMYT1, while sparing WEE1. It also suppressed proliferation of the CCNE1-amplified HCC1569 breast cancer cell line and showed synergistic cytotoxicity in combination with gemcitabine. PKMYT1 X-ray cocrystallography confirmed that introduction of key binding interactions between the inhibitors and residues Asp251 and Tyr121 of PKMYT1 greatly enhanced the potency and selectivity of the compounds.
