Basic leucine zipper transcriptional factor ATF-like 2 (Batf2)

AP-1 family transcription factor that regulates the differentiation of lineage-specific cells from the immune system. Selectively suppresses CYR61/CCN1 transcription and hence blocks the downstream cell proliferation signals produced by CYR61 and inhibits CYR61-induced anchorage-independent growth and invasion in many cancer types.

Maybe acts by interfering with AP-1 binding to CYR61 promoter (By similarity). Following infection, participates in the differentiation of CD8(+) thymic conventional dendritic cells from the immune system.
