The globular C1q (gC1q) domain containing proteins, commonly referred as C1q domain containing (C1qDC) proteins, are an essential family of proteins involved in various innate immune responses. In this study, three novel C1qDC proteins were identified from the disk abalone (Haliotis discus discus) transcriptome database and designated as AbC1qDC1, AbC1qDC2,(More)
Signal transducer and activator of transcription 3 (STAT3) is one of the crucial transcription factors in the Janus kinase (JAK)/STAT signaling pathway, and it was previously considered as acute phase response factor. A number of interleukins (ILs) such as IL-5, IL-6, IL-9, IL-10, IL-12, and IL-22 are known to be involved in activation of STAT3. In(More)
Serine proteases and their inhibitors play vital roles in diverse biological processes. In this study, we identified and characterized cDNA coding for a Kunitz-type serine protease inhibitor (SPI), which we designated as RbKSPI, in a commercially important species, rock bream. The full-length cDNA sequence of RbKSPI consisted of 2452 bp with an open reading(More)
Signal transducer and activator of transcription 2 (STAT2) is a key element that transduces signals from the cell membrane to the nucleus via the type I interferon-signaling pathway. Although the structural and functional aspects of STAT proteins are well studied in mammals, information on teleostean STATs is very limited. In this study, a STAT paralog,(More)
Glutathione S-transferases (GSTs, EC 2.5.1.18) are categorized as phase II enzymes, which form an important multifunctional family associated with a wide variety of catalytic activities. GSTω, GSTρ, and GSTθ are cytosolic GSTs which have been extensively studied in a variety of organisms; however, few studies have focused on teleosts. Those paralogs from(More)
Haptoglobin (Hp) and serum amyloid A (SAA) are two vital proteins involved in inflammatory reactions and are classified as acute-phase proteins. They are released from hepatocytes under inflammatory conditions to protect healthy cells from being damaged by pathogens or from self-destructive mechanisms. In this study, a previously constructed black rockfish(More)
Signal transducers and activators of transcription 1 (STAT1) is critically involved in mediating cytokine-driven signaling, and triggers the transcription of target genes to activate cellular functions. Although the structural and functional aspects of STAT members have been well described in mammals, only limited information is available for the STAT genes(More)
