Acts as a zinc transporter involved in intracellular zinc homeostasis (PubMed:28334855). Functions as a secondary coactivator for nuclear receptors by cooperating with p160 coactivators subtypes. Plays a role in transcriptional activation of Wnt-responsive genes (By similarity). Interacts with GRIP1, ESR1 and AR. Mainly in the cytoplasm (PubMed:10409434). Partial co-localization with endoplasmic reticulum (PubMed:28334855). Ubiquitously expressed in fetal and adult tissues and cancer cell lines. The disease is caused by variants affecting the gene represented in this entry. Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family. SLC30A subfamily. Unlikely isoform. Aberrant splice sites.
