AI Article Synopsis

  • The vascular network is formed and maintained through vasculogenesis and angiogenesis, which require precise cellular processes influenced by small Rho GTPases and the DOCK protein family.
  • Evidence suggests that DOCK proteins, typically linked to neuronal development, also play crucial roles in regulating vascular growth and development through various signaling pathways (like CXCR4, VEGF, and PI3K).
  • The review explores current insights into DOCK proteins' functions in vascular development and their potential link to human vascular diseases and related dysfunctions.

Article Abstract

The vascular network is established and maintained through the processes of vasculogenesis and angiogenesis, which are tightly regulated during embryonic and postnatal life. The formation of a functional vasculature requires critical cellular mechanisms, such as cell migration, proliferation and adhesion, which are dependent on the activity of small Rho GTPases, controlled in part by the dedicator of cytokinesis (DOCK) protein family. Whilst the majority of DOCK proteins are associated with neuronal development, a growing body of evidence has indicated that members of the DOCK family may have key functions in the control of vasculogenic and angiogenic processes. This is supported by the involvement of several angiogenic signalling pathways, including chemokine receptor type 4 (CXCR4), vascular endothelial growth factor (VEGF) and phosphatidylinositol 3-kinase (PI3K), in the regulation of specific DOCK proteins. This review summarises recent progress in understanding the respective roles of DOCK family proteins during vascular development. We focus on existing in vivo and in vitro models and known human disease phenotypes and highlight potential mechanisms of DOCK protein dysfunction in the pathogenesis of vascular disease.

SSNA-1 is a fibrillar protein localized at the area where dynamic microtubule remodeling occurs including centrosomes. Despite the important activities of SSNA1 to microtubules such as nucleation, co-polymerization, and lattice sharing microtubule branching, the underlying molecular mechanism have remained unclear due to a lack of structural information. Here, we determined the cryo-EM structure of SSNA-1 at 4.

Background: Clozapine exhibits significant therapeutic efficacy in schizophrenia, especially treatment-resistant schizophrenia. However, clozapine can cause agranulocytosis, a fatal adverse effect, and the aim of this study is to explore this mechanism based on network pharmacology and molecular docking.

Method: Six and two databases were used to identify targets associated with clozapine and agranulocytosis, respectively.

Lipid nanoparticles (LNP) are the most clinically advanced non-viral gene delivery system. While progress has been made for enhancing delivery, cell specific targeting remains a challenge. Targeting moieties such as antibodies can be chemically-conjugated to LNPs however, this approach is complex and has challenges for scaling up.

Cysimiditides: RiPPs with a Zn-Tetracysteine Motif and Aspartimidylation.

Aspartimidylation is a post-translational modification found in multiple families of ribosomally synthesized and post-translationally modified peptides (RiPPs). We recently reported on the imiditides, a new RiPP family in which aspartimidylation is the class-defining modification. Imiditide biosynthetic gene clusters encode a precursor protein and a methyltransferase that methylates a specific Asp residue, converting it to aspartimide.

Molecular docking methods are widely used in drug discovery efforts. RAS proteins are important cancer drug targets, and are useful systems for evaluating docking methods, including accounting for solvation effects and covalent small molecule binding. Water often plays a key role in small molecule binding to RAS proteins, and many inhibitors─including FDA-approved drugs─covalently bind to oncogenic RAS proteins.
