General annotation (Comments)
| Function | Microtubule-associated protein that mediates aggregation of mitochondria resulting in cell death and genomic destruction (MAGD). Plays a role in anchoring the microtubule-organizing center to the centrosomes. Binds to DNA. Plays a role in apoptosis. Involved in the formation of microtubule bundles By similarity. Ref.12 Ref.15 |
| Subunit 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). Ref.1 Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.14 Ref.25 |
| Subcellular location | Nucleus. Cytoplasm › cytosol. Cytoplasm › cytoskeleton. Cytoplasm › cytoskeleton › spindle. Note: Detected in filopodia-like protrusions and synapses By similarity. Detected in perinuclear punctate network corresponding to mitochondrial aggregates and in the nucleus in cells exhibiting apoptosis. Associated specifically with microtubules stabilized by paclitaxel and colocalizes with RASSF1 isoform A. In interphase cells, shows a diffuse cytoplasmic staining with partial localization to the microtubules. During the different stages of mitosis detected at the spindle microtubules. Ref.8 Ref.11 Ref.12 Ref.15 |
| Tissue specificity | Expressed in neurons (at protein level). Expressed in spermatocytes, spermatids and spermatozoa. Expressed in the cerebral cortex. Highly expressed in testis. Moderately expressed in the brain, colon, heart, kidney, liver, lung, placenta, small intestine, spleen and stomach. Weakly expressed in muscle. Ref.1 Ref.7 Ref.14 |
| Domain | The N-terminus of the heavy chain associates with the C-terminus of the light chain to form the heterodimer complex By similarity. Its C-terminal part of the heavy chain interacts with ESR1. |
| Miscellaneous | 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. |
| Sequence similarities | Belongs to the MAP1 family. |
| Sequence caution | The sequence AAH07253.1 differs from that shown. Reason: Erroneous initiation. The sequence AAH07253.1 differs from that shown. Reason: Contaminating sequence. At the N-terminus.
