There is no clear separation between noise and signal. Pfam:PF00053 is very similar, but has 8 instead of 6 conserved cysteines. Includes some cytokine receptors. The EGF domain misses the N-terminus regions of the Ca2+ binding EGF domains (this is the main reason of discrepancy between swiss-prot domain start/end and Pfam). The family is hard to model due to many similar but different sub-types of EGF domains. Pfam certainly misses a number of EGF domains.

hEGF, or human growth factor-like EGF, domains have six conserved residues disulfide-bonded into the characteristic 'ababcc' pattern. They are involved in growth and proliferation of cells, in proteins of the Notch/Delta pathway, neurogulin and selectins. hEGFs are also found in mosaic proteins with four-disulfide laminin EGFs such as aggrecan and perlecan. The core fold of the EGF domain consists of two small beta-hairpins packed against each other. Two major structural variants have been identified based on the structural context of the C-terminal Cys residue of disulfide 'c' in the C-terminal hairpin: hEGFs and cEGFs. In hEGFs the C-terminal thiol resides in the beta-turn, resulting in shorter loop-lengths between the Cys residues of disulfide 'c', typically C[8-9]XC. These shorter loop-lengths are also typical of the four-disulfide EGF domains, laminin ad integrin. Tandem hEGF domains have six linking residues between terminal cysteines of adjacent domains. hEGF domains may or may not bind calcium in the linker region. hEGF domains with the consensus motif CXD4X[F,Y]XCXC are hydroxylated exclusively in the Asp residue.

This domain is found in human Protein jagged-1 (JAG1) and similar sequences mainly found in animals. JAG1 is a ligand for multiple Notch receptors and involved in the mediation of Notch signalling. This protein shows a large extracellular region made of a poorly characterized N-terminal region (Pfam:PF07657), a DSL (Delta/Serrate/Lag-2) domain (Pfam:PF01414), a series of 16 epidermal growth factor (EGF) tandem repeats, and a cysteine-rich juxtamembrane region. This entry represents the second atypical EGF domain, which constitutes the receptor binding region of JAG1 together with the DSL domain and the first atypical EGF domain [6].
This entry represents a region of conserved sequence at the N terminus of several Notch ligand proteins. The entry has been extended to correspond to the C2-like domain defined by the protein structure.
