General description

The COL1A1 (collagen type I α 1 chain) gene codes for the pro-α1 chains of type I collagen. The triple helix of the type I collagen is composed of two α chains and this protein is localized to connective tissues and predominantly expressed in bone, cornea, dermis and tendon. COL1A1 is mapped to human chromosome 17q21.33. 90% of the bone matrix comprises of collagen type I.


COL1A1 (NP_000079.1, 1021 a.a. ~ 1108 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.


Physical form

Solution in phosphate buffered saline, pH 7.4

Biochem/physiol Actions

Proteins belonging to the collagen family, supports and nourishes body tissues such as tendons, cartilage, skin, and sclera of the eye. Mutation in COL1A1 (collagen type I α 1 chain) gene is associated with a number of connective tissue disorders such as Ehlers-Danlos syndrome type VIIA, Ehlers-Danlos syndrome Classical type, osteogenesis imperfecta types I-IV, idiopathic osteoporosis and Caffey Disease. The COL1A1 is associated with a particular type of skin tumor called dermatofibrosarcoma protuberans which is due to over expression of growth factors. Two transcripts, resulting from the use of alternate polyadenylation signals, have been identified for this gene.
