- 요약Heme is a ubiquitously expressed small molecule modulator of protein function that participates in enzymatic reactions as a prosthetic group and acts as a signaling molecule to coordinate several facets of metabolism. Upon cellular damage, unbound "free" heme is released from cells and the heme binding proteins they contain, leading to oxidative damage of cellular components and activating inflammatory signals, serving as a damage-associated molecular pattern. In this context, free heme plays a pivotal role in pathological mechanisms of sterile and pathogenic hemolytic conditions, such as malaria, hemolytic anemias, and injury causing hemorrhage. Heme has been speculated to stimulate immune cells such as leukocytes through activation of precise signaling pathways via direct binding to innate immune receptors. However, the mechanisms by which heme causes the activation of pro-inflammatory responses is not fully understood. This is due to a lack of available tools to study transient heme-protein interactions in native systems. Here, we describe a strategy which utilizes a heme-based photoaffinity probe integrated with chemical proteomic methods to map heme-protein interactions across the proteome. We aim to elucidate specific proteins and biochemical pathways involved in the regulation of heme-dependent signaling functions in immune cells and ascertain the functional consequences and roles of identified immunomodulatory proteins in heme-induced signaling; we highlight examples such as CD36, a heme binding protein identified herein and annotated multifunctional scavenger receptor involved in pattern recognition and activation of immune cells and IRAK1, a pro-inflammatory signaling kinase which serves as a critical signaling node in toll-like receptor-mediated pattern recognition and inflammation.
