Its structure has been solved and shown to have a C-lectin type of structure [1]. Intimin is a bacterial adhesion molecule involved in intimate attachment of enteropathogenic and enterohemorrhagic Escherichia coli to mammalian host cells. Intimin targets the translocated intimin receptor (Tir), which is exported by the bacteria and integrated into the host cell plasma membrane.	Domain

This entry represents the fifth Ig-like domain in NUP210 proteins. NUP210 proteins are membrane glycoproteins that are integral components of the nuclear pore complex. These proteins are essential for the assembly and fusion of nuclear pores, maintaining proper nuclear pore spacing, and ensuring the structural integrity of the nuclear envelope. They are known to form dimers and potentially higher-order oligomers, which may contribute to their functional roles in the nuclear pore complex. NUP210 proteins are composed of multiple immunoglobulin-like (Ig-like) domains that form a ring around the NPC within the NE lumen [1-2].	Domain
A [auth I]	PF02369	Bacterial Ig-like domain (group 1) (Big_1)	Bacterial Ig-like domain (group 1)	This family consists of bacterial domains with an Ig-like fold. Members of this family are found in bacterial surface proteins such as intimins and invasins involved in pathogenicity.	Domain
