Rps19bp1, the function of which is not fully elucidated, has been associated with multiple biological processes. It is involved in ribosome biogenesis as it participates in 40 S ribosomal subunit assembly, which in turn promotes erythropoiesis [1]. Additionally, it may be related to protein-folding processes in pancreatic β-cells, as its expression was altered in diabetic β-cells [3].

In a study using conditional knockout mouse models, depletion of Atf4 in hematopoietic cells led to erythroid differentiation defects due to the down-regulation of Rps19bp1. ATF4 was found to directly regulate Rps19bp1 transcription, highlighting the importance of the ATF4-Rps19bp1 axis in promoting erythropoiesis [1]. In prostate cancer, the LINC00106/Rps19bp1/p53 axis was identified, where LINC00106 and Rps19bp1 interact to prevent p53 activity, promoting the proliferation and migration of prostate cancer cells [2].

In conclusion, Rps19bp1 is crucial for erythropoiesis through its role in ribosome biogenesis and may also contribute to cancer-related processes such as the proliferation and migration of prostate cancer cells. The use of gene knockout and conditional knockout mouse models has significantly enhanced our understanding of Rps19bp1's functions in erythropoiesis and cancer-related biological processes.
