Rabbit anti-Human MAD1L1 Polyclonal Antibody

Uniprot Id

Q9Y6D9

Target Species

Human

Target Name

MAD1L1

Target Full Name

Mitotic spindle assembly checkpoint protein MAD1

Target Function

Component of the spindle-assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. Forms a heterotetrameric complex with the closed conformation form of MAD2L1 (C-MAD2) at unattached kinetochores during prometaphase, recruits an open conformation of MAD2L1 (O-MAD2) and promotes the conversion of O-MAD2 to C-MAD2, which ensures mitotic checkpoint signaling.; Sequesters MAD2L1 in the cytoplasm preventing its function as an activator of the mitotic spindle assembly checkpoint (SAC) resulting in SAC impairment and chromosomal instability in hepatocellular carcinomas.

Target Involvement

Defects in MAD1L1 are involved in the development and/or progression of various types of cancer.

Target Subcellular Location

Nucleus. Chromosome, centromere, kinetochore. Nucleus envelope. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytoskeleton, spindle. Cytoplasm, cytoskeleton, spindle pole.; [Isoform 3]: Cytoplasm.

Target Background

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. Alternative splicing results in multiple transcript variants.
