Myosin VI Is Associated With the Endoplasmic Reticulum in Regions of Sertoli Cells Containing Tubulobulbar Complexes

open access: yesCytoskeleton, EarlyView.
ABSTRACT Myosin VI has been reported by others to localize in association with various regions of apical tubulobulbar complexes (TBCs) at sites of attachment between Sertoli cells and late spermatids in the mouse. Tubulobulbar complexes internalize “intact” intercellular junctions during sperm release and during spermatocyte translocation through the ...

TRiC Is a Structural Component of Mammalian Sperm Axonemes

open access: yesCytoskeleton, EarlyView.
ABSTRACT The TRiC chaperonin is responsible for folding ~5%–10% of the proteome in eukaryotic cells. Our recent cryo‐electron microscopy studies of axonemes from diverse mammalian cell types led to the surprising discovery that a fully assembled TRiC chaperonin is a structural component of mammalian sperm flagella, where it is tethered to the radial ...

Blind User Activity Detection for Grant-Free Random Access in Cell-Free mMIMO Networks [PDF]

open access: yesarXiv
Cell-free massive MIMO (CF-mMIMO) networks have recently emerged as a promising solution to tackle the challenges arising from next-generation massive machine-type communications. In this paper, a fully grant-free deep learning (DL)-based method for user activity detection in CF-mMIMO networks is proposed.

Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly

open access: yesCytoskeleton, EarlyView.
ABSTRACT The primary cilium serves as an antenna of most vertebrate cells and is important for conveying cues from several signaling pathways into appropriate cellular responses during development and homeostasis. Cilia assembly and disassembly processes are thought to be strictly controlled; however, the precise nature of molecular events underlying ...

Functional, pathogenic, and pharmacological roles of protein folding intermediates

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView., 2023
Abstract Protein expression and function in eukaryotic cells are tightly harmonized processes modulated by the combination of different layers of regulation, including transcription, processing, stability, and translation of messenger RNA, as well as assembly, maturation, sorting, recycling, and degradation of polypeptides.

Jamming Detection in MIMO-OFDM ISAC Systems Using Variational Autoencoders [PDF]

open access: yesarXiv
This paper introduces a novel unsupervised jamming detection framework designed specifically for monostatic multiple-input multiple-output (MIMO)-orthogonal frequency-division multiplexing (OFDM) radar systems. The framework leverages echo signals captured at the base station (BS) and employs the latent data representation learning capability of ...
