Summary
[Homo sapiens] HSP90B1 amplifies innate and adaptive immune responses via interaction with TLR2 and TLR4 ligands.
[Homo sapiens] Absence of HSP90B1 results in a defect in the formation of some cell surface receptors including Toll-like receptors (TLRs) which, as a result, are retained intracellularly.
[Homo sapiens] HSP90B1 is an endoplasmic reticulum master chaperone for multiple TLRs and is also essential for expression of multiple hematopoietic system-specific integrins.
[Homo sapiens] HSP90B1, an endoplasmic reticulum chaperone, is required in vesicular stomatitis virus (VSV) infection and in innate immunity via Toll-like receptors (TLRs). TLR-mediated immunity maintains the broad host range of the envelope glycoprotein of VSV (VSV-G) by positively selecting for the ubiquitous expression of HSP90B1.
[Homo sapiens] HSP90B1 chaperones multiple Toll-like receptors (TLRs), but not TLR3, in a manner that is dependent on another endoplasmic reticulum (ER) luminal protein, CNPY3.
[Homo sapiens] HSP90B1 on the surface of polymorphonuclear leukocytes (PMNs) serves as a receptor for Escherichia coli K1 (EC-K1) entry into the cell. EC-K1 exploits surface-expressed HSP90B1 in PMNs to prevent oxidative burst for the onset of neonatal meningitis. (Demonstrated in mice)

Entrez Gene
Summary This gene does not have any Entrez summary - the following is the summary from its human ortholog ENSG00000166598:
microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009] This gene encodes a member of a family of adenosine triphosphate(ATP)-metabolizing molecular chaperones with roles in stabilizing and folding other proteins. The encoded protein is localized to melanosomes and the endoplasmic reticulum. Expression of this protein is associated with a variety of pathogenic states, including tumor formation. There is a microRNA gene located within the 5' exon of this gene. There are pseudogenes for this gene on chromosomes 1 and 15. [provided by RefSeq, Aug 2012]
