Mitotic spindle assembly checkpoint protein MAD1 is a protein that in humans is encoded by the MAD1L1 gene.[1][2][3]

MAD1L1 is also known as Human Accelerated Region 3. It may therefore have played a key role in differentiating Humans from Apes.

MAD1L1 is a component of the mitotic spindle-assembly checkpoint that prevents the onset of anaphase until all chromosome are properly aligned at the metaphase plate. MAD1L1 functions as a homodimer and interacts with MAD2L1. MAD1L1 may play a role in cell cycle control and tumor suppression. Three transcript variants encoding the same protein have been found for this gene.[3]

Interactions[edit]

Mad1 has been shown to interact with HDAC1,[4] Histone deacetylase 2[4] and MAD2L1.[5][6][7]
