Descripción
Signal regulatory protein beta-1 (SIRPB1) is a transmembrane glycoprotein that is part of the signal regulatory protein (SIRP) family within the immunoglobulin superfamily (IgSF). SIRPB1 is primarily expressed on myeloid cells, such as macrophages, dendritic cells, and granulocytes, and functions as an activating receptor involved in immune regulation, phagocytosis, and cellular signaling. Unlike SIRPA, another family member which interacts with CD47 to deliver inhibitory signals to prevent “self” cell phagocytosis, SIRPB1 typically serves as an activating receptor and does not interact directly with CD47. SIRPB1 plays a role in modulating immune responses, particularly through its association with DAP12 (DNAX activation protein of 12 kDa), an adaptor molecule containing immunoreceptor tyrosine-based activation motifs (ITAMs). Upon activation, SIRPB1 influences signaling cascades that lead to pro-inflammatory cytokine release, phagocytosis, and cellular migration, especially in response to pathogens or tissue injury. Because of its involvement in immune activation, SIRPB1 has become of interest in cancer, infectious diseases, and inflammatory disorders.

The protein encoded by this gene is a member of the signal-regulatory-protein (SIRP) family, and also belongs to the immunoglobulin superfamily. SIRP family members are receptor-type transmembrane glycoproteins known to be involved in the negative regulation of receptor tyrosine kinase-coupled signaling processes. This protein was found to interact with TYROBP/DAP12, a protein bearing immunoreceptor tyrosine-based activation motifs. This protein was also reported to participate in the recruitment of tyrosine kinase SYK. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq].
