Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The MASH1 protein also known as Achaete-Scute homolog 1 (ASCL1) plays an important role in neurogenesis. It acts as a transcription factor and regulates neuronal differentiation. MASH1 has a molecular weight of approximately 34 kDa. It expresses predominantly in the nervous system including the developing neural tube and peripheral ganglia and it can also be found in certain regions of the brain during embryonic development. ASCL1 is part of the basic helix-loop-helix (bHLH) family of transcription factors which are key regulators of neuronal identity and function.
Biological function summary

This protein regulates the expression of genes important for the development of neuronal precursors. MASH1 does not act alone; it forms heterodimers with other bHLH proteins which enhance its ability to bind DNA and influence gene transcription. It helps convert multipotent neural progenitors into committed neuronal precursors which later differentiate into specific neuronal cell types. MASH1's role is particularly important during early stages of neuronal differentiation ensuring proper formation and maturation of the nervous system.

Pathways

MASH1 is central to the Notch signaling pathway and other pathways involved in neural differentiation. Within the Notch pathway MASH1 interacts with proteins like HES1 to balance the differentiation of neural progenitor cells into neurons and glial cells. This protein also connects with other pathway components such as NEUROG2 a downstream target to promote neuronal fate specification. These interactions illustrate MASH1’s integration into complex signaling networks that govern cell fate decisions during neurogenesis.

MASH1 has significant associations with neurodevelopmental disorders and certain cancers. Aberrant ASCL1 activity links to conditions like Hirschsprung's disease where neural crest development is impaired and some types of lung cancer particularly pulmonary neuroendocrine tumors. It is known to interact with the RET protein in the context of Hirschsprung's disease and with proteins like MYC in cancer pathways highlighting its multifaceted involvement in pathology. Understanding these associations helps elucidate the mechanisms of these diseases and supports therapeutic target development.

Target data

Transcription factor that plays a key role in neuronal differentiation : acts as a pioneer transcription factor, accessing closed chromatin to allow other factors to bind and activate neural pathways. Directly binds the E box motif (5'-CANNTG-3') on promoters and promotes transcription of neuronal genes. The combination of three transcription factors, ASCL1, POU3F2/BRN2 and MYT1L, is sufficient to reprogram fibroblasts and other somatic cells into induced neuronal (iN) cells in vitro. Plays a role at early stages of development of specific neural lineages in most regions of the CNS, and of several lineages in the PNS. Essential for the generation of olfactory and autonomic neurons. Acts synergistically with FOXN4 to specify the identity of V2b neurons rather than V2a from bipotential p2 progenitors during spinal cord neurogenesis, probably through DLL4-NOTCH signaling activation. Involved in the regulation of neuroendocrine cell development in the glandular stomach (By similarity).
