Mitotic spindle assembly checkpoint protein MAD2A (Q9Z1B5)

Uniprot ID Q9Z1B5
Protein Name Mitotic spindle assembly checkpoint protein MAD2A
Gene Name Mad2l1
Species Mus musculus (Mouse)
Signal peptide(a) N Secretome P(b) 0.807
Function Component of the spindle-assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. Required for the execution of the mitotic checkpoint which monitors the process of kinetochore-spindle attachment and inhibits the activity of the anaphase promoting complex by sequestering CDC20 until all chromosomes are aligned at the metaphase plate (By similarity). .

(a) The Signal peptide D-score cutoff for "YES"(having signal peptide) is 0.45.
(b) Non-classically secreted proteins should obtain an NN-score(Neural Networks score) exceeding the normal threshold of 0.5, but not at the same time be predicted to contain a signal peptide.
