Abstract

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, and AbC1qDC3. The cDNA sequences of AbC1qDC1, AbC1qDC2, and AbC1qDC3 consisted of 807, 1305, and 660 bp open reading frames (ORFs) encoding 269, 435, and 220 amino acids (aa), respectively. Putative signal peptides and the N-terminal gC1q domain were identified in all three AbC1qDC proteins. An additional predicted motif region, known as the coiled coil region (CCR), was identified next to the signal sequence of AbC1qDC2. The genomic organization of the AbC1qDCs was determined using a bacterial artificial chromosome (BAC) library. It was found that the CDS of AbC1qDC1 was distributed among three exons, while the CDSs of AbC1qDC2 and AbC1qDC3 were distributed between two exons. Sequence analysis indicated that the AbC1qDC proteins shared
