[7] It was later reclassified because of its homology to the FKBP family of proteins and was renamed FKBP-like (FKBPL).

A separate study that found it to be involved in the stabilisation of newly synthesised p21 termed it Wisp39.

[8] It is known to interact with Hsp90, glucocorticoid receptor and dynamitin and may play a role in signalling, like other FKBPs.

[9] FKBPL has also been shown to influence estrogen receptor signalling and can have a determinant effect on response to the breast cancer drug tamoxifen.
