I NSM1 (IA-1) is a transcription factor expressed in embryonic and regenerating adult neural and neuroendocrine tissue. Between different tissues and among different species, a variety of tissue-level functions have been described for INSM1 and its orthologues. Despite the varied functions described, INSM1 is highly conserved in both amino-acid and nucleotide sequence, across organisms ranging from mammals to nematodes. Using olfactory epithelium (OE) as a model tissue, examination of INSM1 expression and function illustrates remarkable similarity in developmental events between OE and other neuroepithelia. Review of molecular and tissue functions of INSM1 orthologues in other systems raises the intriguing possibility that conservation of molecular developmental mechanisms extends to neuroendocrine tissues, as well.
