CDKN1B

gene da espécie Homo sapiens

O inibidor de quinase dependente de ciclina 1B (p27Kip1) é um inibidor de enzima que em humanos é codificado pelo gene CDKN1B.[1] Codifica uma proteína que pertence à família Cip/Kip de proteínas inibidoras da quinase dependente de ciclina (Cdk). A proteína codificada liga-se e previne a activação dos complexos ciclina E - CDK2 ou ciclina D - CDK4 e, assim, controla a progressão do ciclo celular em G1. É frequentemente referida como uma proteína inibidora do ciclo celular porque a sua principal função é interromper ou desacelerar o ciclo de divisão celular.
