背景信息

C1q-like protein 1 (C1QL1) is a secreted glycoprotein belonging to the C1q/tumor necrosis factor (TNF)-related protein (CTRP) family, which shares structural homology with the complement component C1q. It features a characteristic C-terminal globular C1q domain and a short N-terminal collagen-like region. Primarily expressed in the brain, adipose tissue, and endocrine organs, C1QL1 plays multifaceted roles in synaptic organization, metabolic regulation, and cell-cell communication. It interacts with specific neuronal receptors, including brain-specific angiogenesis inhibitor 3 (BAI3), to modulate synaptic plasticity and neural circuit development.

The recombinant C1QL1 protein, produced through heterologous expression systems like mammalian cells (e.g., HEK293 or CHO cells), enables functional studies by providing a controlled, purified form of the native protein. Its recombinant production often includes affinity tags (e.g., His-tag or Fc-fusion) to facilitate purification and detection. Researchers leverage this tool to investigate C1QL1's involvement in energy homeostasis, insulin sensitivity, and neurodegenerative processes. Emerging evidence suggests its potential as a therapeutic target in metabolic disorders, cognitive decline, and obesity-related pathologies. However, challenges persist in replicating native post-translational modifications and quaternary structures critical for receptor binding activity, necessitating rigorous functional validation in experimental models. Current studies focus on mapping its signaling pathways and tissue-specific interactomes to clarify its dual roles in neural and metabolic cross-talk.
