I-set | pfam07679 | Immunoglobulin I-set domain. | ig | pfam00047 | Immunoglobulin domain. Ig: immunoglobulin (Ig) domain found in the Ig superfamily. The Ig superfamily is a heterogenous group of proteins, built on a common fold comprised of a sandwich of two beta sheets. Members of this group are components of immunoglobulin, neuroglia, cell surface glycoproteins, such as, T-cell receptors, CD2, CD4, CD8, and membrane glycoproteins, such as, butyrophilin and chondroitin sulfate proteoglycan core protein. A predominant feature of most Ig domains is a disulfide bridge connecting the two beta-sheets with a tryptophan residue packed against the disulfide bond. | CD4-extracel | pfam09191 | CD4, extracellular. Members of this family adopt an immunoglobulin-like beta-sandwich, with seven strands in 2 beta sheets, in a Greek key topology. They are predominantly found in the extracellular portion of CD4 proteins, where they enable interaction with major histocompatibility complex class II antigens. | V-set | pfam07686 | Immunoglobulin V-set domain. This domain is found in antibodies as well as neural protein P0 and CTL4 amongst others. |
