The 20-kDa growth hormone (GH) is generated from alternative splicing of the primary transcript of full-length 22-kDa GH. We have studied the regulation of 20-kDa GH over a range of pathophysiological conditions and in response to pharmacological stimulation using isoform-specific enzyme-linked immunosorbent assays (ELISAs). Mean 24-h levels of 20- and 22-kDa GH were higher in acromegaly and lo...

Japanese encephalitis virus (JEV), a mosquito-borne flavivirus, is closely related to West Nile (WN), yellow fever (YF), and dengue (DEN) viruses. Its plus-strand genomic RNA carries a single open reading frame encoding a polyprotein that is cleaved into three structural (C, prM/M, and E) and at least seven nonstructural (NS1/NS1', NS2A, NS2B, NS3, NS4A, NS4B, and NS5) proteins, based on previo...

the leishmania major parasite surface antigen-2 (psa-2) is a family of glycoinositol phospholipids anchored glycoprotoins expressed in both promastigotes and amastigotes. promastigote psa-2 comprises three polypeptides with approximate molecular weight of 96, 80 and 50 kda. amastigote express a distinct but closely psa-2 polypeptide with molecular weight of 50 kda. in this study fusion of sp2/0...

OBJECTIVES In contrast to peripheral nerves, central neurons do not regrow spontaneously after injury. Our previous studies showed that transplantation of degenerating peripheral nerves or their extracts can induce regeneration in the injured central nervous system. Non-predegenerated nerves show much weaker neurotrophic activity. The aim of the present work was to examine quantitatively and qu...

Protein Description 393 amino acids; 53 kDa phosphoprotein; contains, from N-term to C-term, a transactivation domain, a DNA-binding domain, nuclear localization signals and a tetramerization domain. Expression Widely expressed. Localisation Nucleus. Function Tumour suppressor gene; P53 is a transcriptional regulator acting as a guardian of the genome; in response to DNA damage, p53 is overexpr...

The thiol-specific photoactivatable reagent benzophenone-4-iodoacetamide can be incorporated into myosin subfragment 1 (S1), accompanied by an increase of Ca2+-ATPase and the loss of K+-ATPase activities, a characteristic property of S1 when reactive sulfhydryl 1 (SH-1) is modified. After trypsin cleavage, 25-kDa, 50-kDa, and 20-kDa fragments were found upon NaDodSO4/polyacrylamide gel electrop...

Proteolytic digestion and indirect immunostaining were used to compare the platelet and sarcoplasmic reticulum Ca2+-ATPase proteins. When the platelet and sarcoplasmic reticulum Ca2+-ATPase proteins were digested in the native state with trypsin, the platelet Ca2+-ATPase, which had an apparent undigested molecular mass of 103 kDa, yielded 78-kDa and 25-kDa fragments. Calcium transport activity ...

This review pretends to shed light on the immune processes occurring in coronavirus disease 2019 (COVID-19) from a perspective based antigens size, lower or larger than 70 kDa. cutoff size point explains host type of response against antigenic proteins severe acute respiratory syndrome 2 (SARS-CoV-2), which may lead development memory B cells or, conversely, suppression, apoptosis, viral escape...
