Osteogenesis imperfecta (OI) is a rare congenital disorder characterized by bone fragility and fractures, and associated with bone deformity, short stature, dentin, ligament and blue‑gray eye sclera. OI is caused by a heterozygous mutation in collagen α‑1(I) chain (COL1A1) or collagen α‑2(I) chain (COL1A2) genes that encode α chains of type I collagen. Collagen α chain peptide contains an N‑pro...

Many soluble plant vacuolar proteins are sorted away from secreted proteins into small vesicles at the trans-Golgi network by transmembrane cargo receptors. Cleavable vacuolar sorting signals include the NH 2 -terminal propeptide (NTPP) present in sweet potato sporamin (Spo) and the COOH-terminal propeptide (CTPP) present in barley lectin (BL). These two proteins have been found to be transport...

Barley lectin is synthesized as a preproprotein with a glycosylated carboxyl-terminal propeptide (CTPP) that is removed before or concomitant with deposition of the mature protein in vacuoles. Expression of a cDNA clone encoding barley lectin in transformed tobacco plants results in the correct processing, maturation, and accumulation of active barley lectin in vacuoles [Wilkins, T.A., Bednarek...

Mice lacking type II collagen fail to develop intervertebral discs. The present study describes the distribution of the developmentally expressed type IIA procollagen molecule, as well as types I and III collagens, in human IV disc specimens ranging from 42 to 101 days gestation. Type IIA procollagen contains the alternatively spliced exon 2 which encodes a 69-amino-acid cysteine-rich domain. B...

Bone loss in rheumatoid arthritis (RA) patients results from chronic inflammation and can lead to osteoporosis and fractures. A few bone remodeling markers have been studied in RA witnessing bone formation (osteocalcin), serum aminoterminal propeptide of type I collagen (PINP), serum carboxyterminal propeptide of type I collagen (ICTP), bone alkaline phosphatase (BAP), osteocalcin (OC), and bon...

In this article, the full description of a heart failure with reduced ejection fraction (HF_REF) cohort of 192 patients is provided. Tables with the baseline demographic, prior history, ECG parameters, echocardiographic parameters, laboratory values and pharmacological treatment of these patients are included. Also, the quartile values of the analyzed circulating biomarkers: high sensitivity Tr...

In 44 consecutive patients with systemic sclerosis (SSc), plasma concentrations of von Willebrand factor (vWf) were higher than those of the vWf propeptide, but the propeptide showed less variability within patient subgroups. Higher values of the propeptide were observed in patients with early pulmonary involvement. A closer correlation of the propeptide than of vWf to biochemical markers of ac...

A 355 cauliflower mosaic virus promoter and a tapetum-specific promoter were used to direct the synthesis in tobacco of preproactinidin and a derivative that lacked a C-terminal extension. Preproactinidin was processed into a form that migrated identically on protein gels with mature actinidin extracted from kiwifruit. This protein was proteolytically active in vitro, and high-level accumulatio...
