CC -!- FUNCTION: Acts as a Mg(2+) transporter. Can also transport other
CC divalent cations such as Ba(2+), Mn(2+), Sr(2+) and Co(2+) but to a
CC much less extent than Mg(2+) (By similarity). May be a receptor for
CC ligands (trioxilins A3 and B3) from the hepoxilin pathway.

CC -!- DISEASE: Ichthyosis, congenital, autosomal recessive 6 (ARCI6)
CC [MIM:612281]: A form of autosomal recessive congenital ichthyosis, a
CC disorder of keratinization with abnormal differentiation and
CC desquamation of the epidermis, resulting in abnormal skin scaling over
CC the whole body. The main skin phenotypes are lamellar ichthyosis (LI)
CC and non-bullous congenital ichthyosiform erythroderma (NCIE), although
CC phenotypic overlap within the same patient or among patients from the
CC same family can occur. Lamellar ichthyosis is a condition often
CC associated with an embedment in a collodion-like membrane at birth;
CC skin scales later develop, covering the entire body surface. Non-
CC bullous congenital ichthyosiform erythroderma characterized by fine
CC whitish scaling on an erythrodermal background; larger brownish scales
CC are present on the buttocks, neck and legs.
CC {ECO:0000269|PubMed:15317751, ECO:0000269|PubMed:17557927,
CC ECO:0000269|PubMed:26456858}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the NIPA family. {ECO:0000305}.
