Ready-to-use ELISA kits are available for the detection of menage a trois 1, an alias of the protein, MNAT1 component of CDK activating kinase. The official gene symbol is MNAT1. The protein, with a mass of 35.8 kDa and length of 309 residues, is reported to be nuclear. It may be known by other names, including: cyclin G1 interacting protein, RING finger protein MAT1, MNAT1 CDK activating kinase assembly factor, MNAT CDK-activating kinase assembly factor 1, CDK7/cyclin-H assembly factor, and CDK-activating kinase assembly factor MAT1, and menage a trois homolog 1 cyclin H assembly factor.
