LAS1L is a nucleolar protein essential for 60S ribosomal subunit maturation. It is part of the PeBoW complex (Pescadillo, BOP1, WDR12) required for processing of 27S pre-rRNA to mature 28S rRNA. Defects in ribosome biogenesis lead to translational deficits that particularly affect highly metabolic cells like neurons.
LAS1L (LAS1 Like Ribosome Biogenesis Factor) (LAS1L product) contains characteristic domains for its function. The protein localizes to Nucleolus and participates in key cellular processes.
