Structure and Function of Human Matrix Metalloproteinases

Cells, 2020
The extracellular matrix (ECM) is a macromolecules network, in which the most abundant molecule is collagen. This protein in triple helical conformation is highly resistant to proteinases degradation, the only enzymes capable of degrading the collagen ...

Phases of large $N$ vector Chern-Simons theories on $S^2 \times S^1$

, 2013
We study the thermal partition function of level $k$ U(N) Chern-Simons theories on $S^2$ interacting with matter in the fundamental representation. We work in the 't Hooft limit, $N,k\to\infty$, with $\lambda = N/k$ and $\frac{T^2 V_{2}}{N}$ held fixed ...

Extended k-Gamma and k-Beta Functions of Matrix Arguments

Mathematics, 2020
Various k-special functions such as k-gamma function, k-beta function and k-hypergeometric functions have been introduced and investigated. Recently, the k-gamma function of a matrix argument and k-beta function of matrix arguments have been presented ...

MVG Mechanism: Differential Privacy under Matrix-Valued Query

, 2018
Differential privacy mechanism design has traditionally been tailored for a scalar-valued query function. Although many mechanisms such as the Laplace and Gaussian mechanisms can be extended to a matrix-valued query function by adding i.i.d.

Some Representations of the Modified Degenerate Gamma Matrix Function [PDF]

Sahand Communications in Mathematical Analysis
The main goal of this article is to extend the concept of special matrix functions through the study of modified degenerate Gamma matrix function. For this, the modified degenerate Gamma matrix function has been introduced and some of its properties have

$BC_2$ type multivariable matrix functions and matrix spherical functions

, 2021
Matrix spherical functions associated to the compact symmetric pair $(\mathrm{SU}(m+2), \mathrm{S}(\mathrm{U}(2)\times \mathrm{U}(m))$, having reduced root system of type $\mathrm{BC}_2$, are studied. We consider an irreducible $K$-representation $(π,V)$ arising from the $\mathrm{U}(2)$-part of $K$, and the induced representation $\mathrm{Ind}_K^G π ...

Endocytic recycling is central to circadian collagen fibrillogenesis and disrupted in fibrosis

eLife
Collagen-I fibrillogenesis is crucial to health and development, where dysregulation is a hallmark of fibroproliferative diseases. Here, we show that collagen-I fibril assembly required a functional endocytic system that recycles collagen-I to assemble ...

Lysosomal Function Impacts the Skeletal Muscle Extracellular Matrix

Journal of Developmental Biology, 2021
Muscle development and homeostasis are critical for normal muscle function. A key aspect of muscle physiology during development, growth, and homeostasis is modulation of protein turnover, the balance between synthesis and degradation of muscle proteins.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Commutators Involving Matrix Functions

The Electronic Journal of Linear Algebra, 2018
Some results are obtained for matrix commutators involving matrix exponentials $\left(\left[e^{A},B\right],\left[e^{A},e^{B}\right]\right)$ and their norms.
