Expression:
P07225 PROS_HUMAN:

Plasma.

Description:
This gene encodes a vitamin K-dependent plasma protein that functions as a cofactor for the anticoagulant protease, activated protein C (APC) to inhibit blood coagulation. It is found in plasma in both a free, functionally active form and also in an inactive form complexed with C4b-binding protein. Mutations in this gene result in autosomal dominant hereditary thrombophilia. An inactive pseudogene of this locus is located at an adjacent region on chromosome 3. [provided by RefSeq, Feb 2009]

Research Backgrounds

Function:

Anticoagulant plasma protein; it is a cofactor to activated protein C in the degradation of coagulation factors Va and VIIIa. It helps to prevent coagulation and stimulating fibrinolysis.

PTMs:

The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.

Application: WB    Species: Human    Sample: Wound granulation tissues

Figure 4. Validation of the protein expression levels of CTSS, PROS1, ITIH4 and PRDX2. Wound granulation tissues from eight patients with diabetic foot ulcers before and after NPWT were collected and subjected to western blotting. Primary antibodies against (A) CTSS, (B) PROS1, (C) ITIH4 and (D) PRDX2 were used to detect differences in protein levels. (A1-D1) Protein bands from four representative patients prior to NPWT (designated as minus symbol ‘−’) and following NPWT (designated as plus symbol ‘+’) are presented in the left panel. Protein samples from the same patients were loaded next to each other. (A2-D2) Then, eight pairs of protein samples from eight patients were analyzed by ImageJ and are depicted as paired dots in the right panel. (A3-D3) The gray level of the target protein was compared with the internal reference (β-actin) gray level to obtain the relative expression value. Paired t-tests were performed and significant changes are indicated by ***P<0.001 vs. before NPWT. CTSS, cathepsin; PROS1, protein S isoform 1; ITIH4, inter α-trypsin inhibitor heavy chain H4; PRDX2, peroxiredoxin-2; NPWT, negative-pressure wound therapy.
