Genes affected

FOXH1 (HGNC:3814): (forkhead box H1) FOXH1 encodes a human homolog of Xenopus forkhead activin signal transducer-1. FOXH1 protein binds SMAD2 and activates an activin response element via binding the DNA motif TGT(G/T)(T/G)ATT. [provided by RefSeq, Jul 2008]

FOXH1 links:

KIFC2 (HGNC:29530): (kinesin family member C2) Predicted to enable microtubule binding activity and microtubule motor activity. Predicted to be involved in microtubule-based movement and mitotic spindle assembly. Predicted to be located in cytoplasm. Predicted to be part of kinesin complex. Predicted to be active in microtubule cytoskeleton and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
