MAP1S

MAP1S (Microtubule Associated Protein 1S) is a Protein Coding gene. Gene Ontology (GO) annotations related to this gene include identical protein binding and actin filament binding. An important paralog of this gene is MAP1B.

microtubule-associated protein 1S

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).

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.
