Background: CLC

Cardiotrophin-like cytokine (CLC) (also known as novel neurotrophin-1 (NNT-1) and B cell stimulating factor (BSF-3)) is a recently discovered 22-25 kDa member of the IL-6 family of cytokines (1, 2, 3). As such, it is expressed as a long type I cytokine with four alpha-helices in it structure (2). Human CLC is synthesized as a 225 amino acid precursor that contains a 27 aa signal sequence and a 198 aa mature region. It contains one potential N-linked glycosylation site that is apparently utilized, and two distinct binding sites for CNTFR alpha and CLF (4, 5). Although CLC has a signal sequence, it is not secreted unless noncovalently dimerized to either CLF or soluble CNTFR alpha (5, 6). Once dimerized, CLC signals through a tripartite receptor complex composed of gp130, LIFR beta and CNTFR alpha (membrane-bound) (5, 7). Within the IL-6 family, human CLC is most homologous to cardiotrophin-1, sharing approximately 29% amino acid sequence identity (8).  Human to mouse, mature CLC is 96% aa identical. CLC is a trophic factor for motor neurons, a stimulator of ACTH release from corticotrophs, and an inducer of IgE synthesis and B cell proliferation (9, 10, 11). Cells known to express CLC include embryonic muscle, lung epithelium, and mesenchyme in various regions (12).
