Figure 5. Schematic illustration of type XII collagen, TGFBIp, and the species purified from porcine cornea.

Figure 5

Human type XII collagen exists as a long and a short splice-variant. Porcine type XII collagen (accession no. XP_001927071) has not been characterized at the protein level at this point, but the sequence of the predicted protein is more than 90% identical to that of human type XII collagen. The fragment of porcine type XII collagen purified in the present study (protein band 4 (151 kDa) in Figure 2) is shown. The C-terminal part of this fragment (indicated with dashed lines) was not identified by MALDI-MS but is likely to be present due to the size of the band in SDS-PAGE (151 kDa).
