Anti-Grainyhead-like 1 antibodies enable researchers to detect and measure the Grainyhead-like 1 antigen in biological samples. This target is a reported synonym of the GRHL1 gene, which encodes grainyhead like transcription factor 1. This protein is known to function in epidermis development and the regulation of transcription, among other biological roles. The human version of Grainyhead-like 1 has a canonical amino acid length of 618 residues and a protein mass of 70.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include LBP32, MGR, and NH32.
