Function
Insulinoma-associated 1 (INSM1) gene is intronless and encodes a protein containing both a zinc finger DNA-binding domain and a putative prohormone domain. This gene is a sensitive marker for neuroendocrine differentiation of human lung tumors. {{cite journal | vauthors = Mukhopadhyay S, Dermawan JK, Lanigan CP, Farver CF | title = Insulinoma-associated protein 1 (INSM1) is a sensitive and highly specific marker of neuroendocrine differentiation in primary lung neoplasms: an immunohistochemical study of 345 cases, including 292 whole-tissue sections | journal = Modern Pathology | volume = 32 | pages = 100–109 | date = August 2018 | issue = 1 | pmid = 30154579 | doi = 10.1038/s41379-018-0122-7 | s2cid = 52110673 | doi-access = free }}
Interactions
INSM1 has been shown to interact with SORBS1.{{cite journal | vauthors = Xie J, Cai T, Zhang H, Lan MS, Notkins AL | title = The zinc-finger transcription factor INSM1 is expressed during embryo development and interacts with the Cbl-associated protein | journal = Genomics | volume = 80 | issue = 1 | pages = 54–61 | date = July 2002 | pmid = 12079283 | pmc = 1237014 | doi = 10.1006/geno.2002.6800 }}
