| Primary Identifier | IPR038542 | Type | Homologous_superfamily |
| Short Name | Spidroin_C_sf |
| description | Spidroin is spider dragline silk. It is composed of two proteins, major ampullate spidroin 1 (MaSp1) and major ampullate spidroin 2 (MaSp2) []. MaSp1 contains five α-helices []. Spidroins contain repetitive units capped between non-repetitive N-terminal and C-terminal domains, whose composition varies among species and thus determines the variety of mechanical properties of spider silks. The C-terminal domains are conserved among spider silk proteins [].This superfamily represents the C-terminal domain of spidroin. |
