RACK1 maintains mouse hematopoietic stem cells by directly binding to and stabilizing LDB1
Single-cell RNA sequencing indicates that adulthood Rack1 deletion in type I interferon-I-responsive cells leads to aberrant lineage-geneset-scores of transcriptional HSCs and the emergence of stressed HSCs, and Mechanistically, RACK1 prevents HSC loss through maintaining the protein level of LDB1.
