Single-molecule fluorescence resonance energy transfer (smFRET) is a powerful technique for studying the structural dynamics of protein molecules or detecting interactions between protein molecules in real time. Due to the high sensitivity in spatial and temporal resolution, smFRET can decipher sub-populations within heterogeneous native state conformations, which are generally lost in traditional measurements due to ensemble averaging. In addition, the single-molecule reconstitution allows protein molecules to be observed for an extensive period of time and can recapitulate the geometry of the cellular environment to retain biological function.

Mycoplasma pneumoniae (M. pneumoniae) is one of the major pathogens causing community-acquired pneumonia (CAP), and its pathogenic mechanism is not fully understood. Inflammatory response is the most basic and common pathological phenomenon of CAP, but the specific mechanism needs further investigation.

Protein phosphorylation plays a crucial role in regulating a wide range of biological processes, and its dysregulation is strongly linked to various diseases. While many phosphorylation sites have been identified so far, their functionality and regulatory effects are largely unknown. Here, a deep learning model MMFuncPhos, based on a multi-modal deep learning framework, is developed to predict functional phosphorylation sites.

These PTPs bind overlapping sets of ITIM/ITSM-bearing proteins, suggesting that they might have some redundant functions. By studying T cell-specific single and double knockout mice, we found that SHP1 and SHP2 redundantly restrain naïve T cell differentiation to effector and central memory phenotypes, with SHP1 playing the dominant role.

Fertility disorders are a worldwide problem affecting 8-12% of the population, with the male factor substantially contributing to about 40-50% of all infertility cases. Mitochondria, crucial organelles for cellular viability, play a pivotal role in the processes of spermatogenesis and significantly affect sperm quality and their fertilizing ability. Mitochondrial oxidative phosphorylation (OXPHOS) dysfunction, reduced energy supply for sperm, reduced endogenous coenzyme Q (CoQ) levels, and oxidative stress are among the main factors that contribute to male infertility.
