TPRX1 (Tetrapeptide Repeat Homeobox 1) is a Protein Coding gene. Among its related pathways are Preimplantation Embryo. Homeobox genes encode DNA-binding proteins, many of which are thought to be involved in early embryonic development. Homeobox genes encode a DNA-binding domain of 60 to 63 amino acids referred to as the homeodomain. TPRX1 is a member of the TPRX homeobox gene family.
