This family includes tubuliform silk fibroins which are used to protect egg cases. This domain is a structural domain which is found in repeats of up to 20 in many individuals (although this is not necessarily the case). RP1 makes up structural domains in the N terminal while RP2 makes up structural domains in the C terminal. [1]	Domain
