Site-directed mutagenesis of cysteine to serine residues affects heparin binding and mitogenicity in fibroblast growth factor 4 produced in Escherichia coli

open access: yesBiotechnology & Biotechnological Equipment, 2019
The binding activity to heparan sulphate is crucial for the mitogenic activity of fibroblast growth factor 4 (FGF4) in developing mammalian embryos. There are two conserved cysteine residues in FGF family proteins, Cys-84 and Cys-151 in mouse FGF4, and ...

A novel human pain insensitivity disorder caused by a point mutation in ZFHX2

open access: yesBrain : a journal of neurology, 2017
Studies of monogenic heritable pain disorders provide valuable insights into human pain mechanisms. Habib et al. show that a point mutation in the gene ZFHX2 causes an autosomal dominant form of pain insensitivity.

Calmodulin variants associated with congenital arrhythmia impair selectivity for ryanodine receptors

open access: yesFrontiers in Molecular Biosciences, 2023
Among its many molecular targets, the ubiquitous calcium sensor protein calmodulin (CaM) recognizes and regulates the activity of ryanodine receptors type 1 (RyR1) and 2 (RyR2), mainly expressed in skeletal and cardiac muscle, respectively.

Analysis of any point mutation in DNA. The amplification refractory mutation system (ARMS).

open access: yesNucleic Acids Research, 1989
We have improved the "polymerase chain reaction" (PCR) to permit rapid analysis of any known mutation in genomic DNA. We demonstrate a system, ARMS (Amplification Refractory Mutation System), that allows genotyping solely by inspection of reaction ...

A Magnetoelectrochemical Bioassay for Highly Sensitive Sensing of Point Mutations in Interleukin-6 Gene Using TMB as a Hybridization Intercalation Indicator

open access: yesBiosensors, 2023
Point mutations are common in the human DNA genome and are closely related to higher susceptibility to cancer diseases. Therefore, suitable methods for their sensing are of general interest.
