FGF13

The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth, and invasion. This gene is located in a region on chromosome X, which is associated with Borjeson-Forssman-Lehmann syndrome (BFLS), making it a possible candidate gene for familial cases of the BFLS, and for other syndromal and nonspecific forms of X-linked cognitive disability mapping to this region. Alternative splicing of this gene at the 5' end results in several transcript variants encoding different isoforms with different N-termini.

Fibroblast Growth Factor 13

Microtubule-binding protein which directly binds tubulin and is involved in both polymerization and stabilization of microtubules (By similarity).

Through its action on microtubules, may participate in the refinement of axons by negatively regulating axonal and leading processes branching (By similarity).

Plays a crucial role in neuron polarization and migration in the cerebral cortex and the hippocampus (By similarity).

May regulate voltage-gated sodium channels transport and function (PubMed:15282281).

May also play a role in MAPK signaling (By similarity).

Required for the development of axonal initial segment-targeting inhibitory GABAergic synapses made by chandelier neurons (By similarity).
