Zinc finger protein PLAG1 (PLAG1)

Transcription factor whose activation results in up- regulation of target genes, such as IGFII, resulting in uncontrolled cell proliferation: when overexpressed in cultured cells, higher proliferation rate and transformation have been observed. Other target genes like CRLF1, CRABP2, CRIP2, PIGF are strongly induced in cells with PLAG1 induction.

Proto-oncogene whose ectopic expression can trigger the development of pleomorphic adenomas of the salivary gland and lipoblastomas. Overexpression is connected with up-regulation of IGFII, is frequently observed in hepatoblastoma, common primary liver tumor in childhood.
