Recombinant human LAS1L protein is a key focus in understanding cellular RNA processing and ribosome biogenesis. LAS1L (LAS1-like protein) is a homolog of yeast Las1. which functions as an endoribonuclease within the conserved Rix1 complex involved in 28S rRNA maturation. In humans, LAS1L operates in the nucleolus, collaborating with components like NOL9 and the Rix1 complex to cleave internal transcribed spacer regions during rRNA processing. Its role is critical for ribosome assembly, linking it to cell proliferation, stress responses, and developmental pathways.
Recombinant LAS1L is typically expressed in bacterial or mammalian systems to study its enzymatic activity, structural interactions, and regulatory mechanisms. Structural analyses reveal conserved nuclease domains and binding interfaces for RNA/protein partners. Dysregulation of LAS1L is implicated in diseases; reduced expression correlates with ribosomopathies, while overexpression is observed in certain cancers, suggesting potential diagnostic or therapeutic applications. Studies using recombinant LAS1L also explore its phosphorylation-dependent activation and crosstalk with cell-cycle checkpoints. Ongoing research aims to map its interactome and dissect its role in rRNA quality control, offering insights into ribosomopathies and cancer biology. This protein serves as a vital tool for probing ribosome maturation pathways and their disease implications. (Word count: 200)
