Roles of the RNA-binding protein SRSF3 in development and cellular differentiation.

Area of Science:

• Molecular Biology
• Developmental Biology
• Gene Regulation

Background:

• RNA-binding proteins are vital for development and homeostasis.
• The serine/arginine-rich (SR) family, particularly SRSF3, plays key roles.
• Understanding SRSF3 is essential for comprehending gene expression control.

Purpose of the Study:

• To review the multifaceted roles of SRSF3 in biological processes.
• To summarize SRSF3's involvement in RNA metabolism and signaling pathways.
• To highlight SRSF3's expression and function during development.

Main Methods:

• Literature review of SRSF3 research.
• Analysis of SRSF3's structure and regulation.
• Compilation of data on SRSF3's functions in RNA processing and signaling.

Main Results:

• SRSF3 regulates alternative splicing, transcription termination, polyadenylation, RNA stability, nuclear export, and miRNA biogenesis.
• SRSF3 interacts with PDGF, EGF, insulin, JAK/STAT, mTOR, retinoic acid, TGF-β, and Wnt signaling pathways.
• SRSF3 expression patterns and functions are critical in germ cell, early embryo, craniofacial, heart, B cell, hepatocyte, megakaryocyte, and macrophage development.

Conclusions:

• SRSF3 is a highly conserved and essential regulator of gene expression during development.
• Further research into SRSF3's mechanisms will illuminate developmental processes.
• Unanswered questions remain regarding SRSF3's precise functions and regulation.
