Who / What
Tau proteins are a group of six highly soluble isoforms produced by alternative splicing of the MAPT gene. They are abbreviated from “tubulin‑associated unit” and primarily serve to stabilize microtubules in axons.
Background & History
The MAPT gene encodes microtubule‑associated protein tau, from which the six isoforms are derived through alternative splicing. This splicing generates discrete protein variants that differ in their functional properties and localization.
Why Notable
Tau proteins are abundant in central nervous system neurons, especially the cerebral cortex, and play a critical role in maintaining microtubule stability within axons. Their dysfunction and aggregation are linked to neurodegenerative disorders such as Alzheimer’s disease and frontotemporal dementia.
In the News
No recent mainstream coverage is available in the provided data; however, tau research remains a focus of neurological disease studies.
