Why this annotation

Hub genes EBF1 (early B cell factor, master regulator of B lymphopoiesis), CD79A and CD79B (Igα/Igβ, essential B cell receptor signaling components), VPREB1 and VPREB3 (surrogate light chain components of the pre-B cell receptor), DNTT (terminal deoxynucleotidyl transferase, expressed in pro-B/pre-B cells undergoing VDJ recombination), IL7R (IL-7 receptor, critical for B lymphopoiesis), IL2RA (CD25, expressed during early B lymphocyte development), CYGB (cytoglobin, expressed in some progenitor states), UHRF1 (DNA methylation maintenance, active in proliferating progenitors), RETREG1 (reticulophagy, ER quality control). This is a tight early B-lineage progenitor signature: EBF1+DNTT+VPREB1/3+CD79A/B+IL7R defines the pro-B to pre-B cell transition. Very low mean expression (0.031) and 1.9% pct positive is consistent with a rare progenitor population within HPCs. As a neighbor of M51 (lymphoid TFs) and M4 (naive B cells), this module represents the earliest committed B cell progenitor stage in the developmental hierarchy. Concordant genes: EBF1, CD79A, CD79B, VPREB1, VPREB3, DNTT, IL7R, IL2RA, UHRF1.
