FoxC1 (D8A6) Rabbit mAb #8758

Forkhead box (Fox) proteins are a family of evolutionarily conserved transcription factors defined by the presence of a winged helix DNA-binding domain called a Forkhead box (1). In humans, there are over 40 known Fox protein family members, divided into 19 subfamilies, which have evolved to regulate gene transcription in diverse and highly specialized biological contexts throughout development (2). Mutations that disrupt the expression of Fox gene family members have consequently been implicated in a broad array of human disorders, including immunological dysfunction, infertility, speech/language disorders, and cancer (3,4).

FoxC1 (FKHL7, FREAC3) is one of two mammalian FoxC subfamily members. Along with FoxC2, it is expressed in paraxial mesoderm where it functions to promote somitogenesis, myogenesis, and vascular development, possibly under Wnt/β-catenin regulation (5). Mutations in FoxC1 are implicated in anterior segment dysgenesis (ASD) disorders, including congenital glaucoma and Axenfeld-Rieger syndrome (6). Research studies have shown that alterations in FoxC1 expression are linked to breast cancer invasiveness (7,8) and have been shown to modulate proliferation and migration of breast cancer cells in vitro (9).
