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

Function

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.[7]

Interactions

MAD1L1 has been shown to interact with:
