NBL1 protein, identified as a potential tumor suppressor gene in neuroblastoma, plays a crucial role in inhibiting cells from progressing into the critical G1/S stage of the transformation process. Functioning as a homodimer, NBL1 underscores its involvement in regulatory mechanisms governing cellular transformation and emphasizes its potential contributions to maintaining normal cellular growth control. NBL1 Protein, Human (HEK293, His) is the recombinant human-derived NBL1 protein, expressed by HEK293 , with C-His labeled tag.
