A TCP1 ou proteína do complexo T 1, subunidade alfa ou complexo t 1^[a] é unha proteína que en humanos está codificada polo xene TCP1 do cromosoma 6.^[1]^[2]^[3]

Función editar

Este xene codifica unha chaperona molecular que é un membro do complexo TRiC. Este complexo consta de dous aneis idénticos empillados, cada un contén oito proteínas diferentes. Os polipéptidos non pregados entran na cavidade central do complexo e son pregados de maneira dependente do ATP. O complexo prega varias proteínas, incluíndo a tubulina. Caracterizáronse variantes de empalme alternativo transcricional deste xene, que codifican diferentes isoformas.^[3]

Interaccións editar

TCP1 presenta interaccións con PPP4C^[4]^[5] e HDAC3.^[6] A CCT tamén interacciona directamente co receptor 1 de LDL oxidado de tipo lectina (LOX-1), mentres que o seu ligando a lipoproteína de baixa densidade oxidada (OxLDL) disocia CCT de LOX-1.^[7]

Notas a rodapé editar

↑ O termo "TCP-1" ampliouse de forma variada como "proteína do complexo T 1" e "polipéptido do complexo sen rabo 1". O "complexo T" é o mesmo que o complexo sen rabo ou tailless, un locus CCT asociado coa lonxitude do rabo en ratos.
