CIB4 (Calcium and Integrin-Binding protein 4) is a member of the CIB protein family, which is characterized by calcium-binding EF-hand motifs and integrin interaction domains. Initially identified as a binding partner for integrin αIIbβ3 in platelets, CIB4 is ubiquitously expressed across tissues, with notable roles in calcium signaling, cell adhesion, and intracellular trafficking. Structurally, it contains four EF-hand motifs, though only a subset may actively bind calcium, suggesting regulatory versatility in calcium-dependent processes. CIB4 has been implicated in modulating cellular responses to calcium fluctuations, influencing pathways related to apoptosis, cytoskeletal organization, and membrane dynamics.
Recombinant CIB4 protein is engineered to study its biochemical interactions and functional mechanisms *in vitro*. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), it enables exploration of calcium-binding kinetics, integrin-binding specificity, and interactions with other signaling molecules like PAK1 or apoptosis-linked proteins. Studies using recombinant CIB4 have revealed its potential role in diseases, including cancer metastasis (via integrin-mediated cell migration) and genetic disorders such as X-linked intellectual disability and skin fragility syndromes linked to CIB4 mutations. Its recombinant form is critical for structural studies (e.g., crystallography) and screening therapeutic compounds targeting calcium-integrin crosstalk. Despite progress, CIB4’s full physiological scope remains under investigation, particularly its tissue-specific functions and disease associations.
