Iroquois-class homeodomain protein IRX-2, also known as Iroquois homeobox protein 2, is a protein that in humans is encoded by the IRX2 gene.[5][6]

Function

IRX2 is a member of the Iroquois homeobox gene family. Members of this family appear to play multiple roles during pattern formation of vertebrate embryos.[5]

Cancer

IRX2 gene has been observed progressively downregulated in Human papillomavirus-positive neoplastic keratinocytes derived from uterine cervical preneoplastic lesions at different levels of malignancy. [7] For this reason, IRX2 is likely to be associated with tumorigenesis and may be a potential prognostic marker for uterine cervical preneoplastic lesions progression. [7]

gollark: (I still have mgollark, they are just not used)

gollark: Idea: mgollark™ runs the server.

gollark: Idea: eliminate palaiologistry.

gollark: Idea: compute BB(6).

gollark: Essentially, I always win.
