This entry corresponds to the KH0 domain from the FMRP protein [1]. This is a divergent KH domain that was discovered through solving the structure of an N-terminal fragment of the FMRP protein [1]. KH0 does not have the canonical G-X-X-G motif between helices A and B [1]. It has been suggested that this domain may be involved in RNA binding [1].

1: Human FMRP contains an integral tandem Agenet (Tudor) and KH motif in the amino terminal domain. Myrick LK, Hashimoto H, Cheng X, Warren ST; Hum Mol Genet. 2015;24:1733-1740. PMID:25416280
