    1059 amino acids
    Molecular mass:
    112211 Da
    Quaternary structure:
    • Heterodimer of a heavy and a light chain. Interacts with microtubules and actin. Both MAP1S heavy and light chains interact with microtubules. MAP1S light chain interacts with actin. Interacts (via C-terminus) with GAN (via Kelch domains) (By similarity). Interacts with ESR1, LRPPRC, RASSF1 isoform A and isoform C, microtubules and VCY2. Interacts with WDR47 (via N-terminus of light chain).
    • Depletion of MAP1S by RNAi causes mitotic abnormalities that consist of failure to form a stable metaphase plate, premature sister chromatid separation, lagging chromosomes, and multipolar spindles
