Tumour necrosis factor receptor 13C, TALL-1 binding domain (IPR015336)

Short name: TNFR_13C_TALL-1-bd

Overlapping homologous superfamilies


Domain relationships



Cytokines can be grouped into a family on the basis of sequence, functional and structural similarities [PMID: 8095800, PMID: 1377364, PMID: 15335677]. Tumor necrosis factor (TNF) (also known as TNF-alpha or cachectin) is a monocyte-derived cytotoxin that has been implicated in tumour regression, septic shock and cachexia [PMID: 2989794, PMID: 3349526]. The protein is synthesised as a prohormone with an unusually long and atypical signal sequence, which is absent from the mature secreted cytokine [PMID: 2268312]. A short hydrophobic stretch of amino acids serves to anchor the prohormone in lipid bilayers [PMID: 2777790]. Both the mature protein and a partially-processed form of the hormone are secreted after cleavage of the propeptide [PMID: 2777790].

There are a number of different families of TNF, but all these cytokines seem to form homotrimeric (or heterotrimeric in the case of LT-alpha/beta) complexes that are recognised by their specific receptors.

The domain represented by this entry is predominantly found in the tumour necrosis factor receptor superfamily member 13c, BAFF-R and is required for binding to tumour necrosis factor ligand TALL-1 [PMID: 12721620].
