Surface Polymer Network Model and Effective Membrane Curvature Elasticity

open access: yes, 1995
A microscopic model of a surface polymer network - membrane system is introduced, with contact polymer surface interactions that can be either repulsive or attractive and sliplinks of functionality four randomly distributed over the supporting membrane ...

Breathless and Beyond: Anterior Mediastinal Malignant Peripheral Nerve Sheath Tumor as a Rare Neurofibromatosis Type 1 Manifestation

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Malignant peripheral nerve sheath tumors (MPNSTs) can rarely present as anterior mediastinal masses in patients with neurofibromatosis type 1 (NF1), causing respiratory symptoms and diagnostic challenges. Multidisciplinary evaluation, including biopsy and imaging, is essential for diagnosis, with surgical resection as the primary treatment ...

The loss of βΙ spectrin alters synaptic size and composition in the ja/ja mouse

open access: yesFrontiers in Neuroscience
IntroductionDeletion or mutation of members of the spectrin gene family contributes to many neurologic and neuropsychiatric disorders. While each spectrinopathy may generate distinct neuropathology, the study of βΙ spectrin’s role (Sptb) in the brain has

A New method for the capture of surface proteins in Plasmodium falciparum parasitized erythrocyte [PDF]

open access: yes, 2012
Introduction: We propose a new method for the selective labeling, isolation and electrophoretic analysis of the Plasmodium falciparum protein exposed on the erythrocyte cell surface.

Cotranslational folding of proteins on the ribosome.

open access: yes, 2020
Many proteins in the cell fold cotranslationally within the restricted space of the polypeptide exit tunnel or at the surface of the ribosome. A growing body of evidence suggests that the ribosome can alter the folding trajectory in many different ways ...

Developmental mechanism of the periodic membrane skeleton in axons

open access: yeseLife, 2014
Actin, spectrin, and associated molecules form a periodic sub-membrane lattice structure in axons. How this membrane skeleton is developed and why it preferentially forms in axons are unknown.

Properties of brain spectrin (fodrin)

open access: yesFEBS Letters, 1983
Fodrin, a protein from bovine brain, immunologically related to spectrin, is shown, unlike some other proteins of generally similar appearance in the electron microscope, to resemble spectrin closely in its most distinctive structural characteristic, the very high α‐helix content. Like spectrin, it is also insoluble below pH 5. One of the subunits only

Loop-closure events during protein folding: Rationalizing the shape of Phi-value distributions

open access: yes, 2005
In the past years, the folding kinetics of many small single-domain proteins has been characterized by mutational Phi-value analysis. In this article, a simple, essentially parameter-free model is introduced which derives folding routes from native ...
