Ensconsin

The product of this gene is a microtubule-associated protein that is predominantly expressed in cells of epithelial origin. Microtubule-associated proteins are thought to be involved in microtubule dynamics, which is essential for cell polarization and differentiation. This protein has been shown to be able to stabilize microtubules, and may serve to modulate microtubule functions. Studies of the related mouse protein also suggested an essential role in microtubule function required for spermatogenesis.

In addition, MAPs also play a role in regulating cellular transport. MAP7 is a necessary cofactor to activate and subsequently transport cargos by Kinesin-1. {{cite journal | vauthors = Hooikaas PJ, Martin M, Mühlethaler T, Kuijntjes GJ, Peeters CA, Katrukha EA, Ferrari L, Stucchi R, Verhagen DG, van Riel WE, Grigoriev I, Altelaar AF, Hoogenraad CC, Rüdiger SG, Steinmetz MO, Kapitein LC, Akhmanova A | display-authors = 6 | title = MAP7 family proteins regulate kinesin-1 recruitment and activation | journal = The Journal of Cell Biology | volume = 218 | issue = 4 | pages = 1298–1318 | date = April 2019 | pmid = 30770434 | doi = 10.1083/jcb.201808065 | pmc = 6446838 }} {{cite journal | vauthors = Monroy BY, Tan TC, Oclaman JM, Han JS, Simó S, Niwa S, Nowakowski DW, McKenney RJ, Ori-McKenney KM | display-authors = 6 | title = A Combinatorial MAP Code Dictates Polarized Microtubule Transport | journal = Developmental Cell | volume = 53 | issue = 1 | pages = 60–72.e4 | date = April 2020 | pmid = 32109385 | doi = 10.1016/j.devcel.2020.01.029 | pmc = 7181406 }}
