Post-translational modificationi

Phosphorylation of Ser-1026 by PKA increases the binding of CA2 and changes the Na+:HCO3- stoichiometry of the transporter from 3:1 to 2:1. Phosphorylated in presence of STK39 and dephosphorylated in presence of PP1 phosphatase; phosphorylation seems to inhibit SLC4A4 activity.By similarity
N-glycosylation is not necessary for the transporter basic functions.1 Publication

Expressioni

Tissue specificityi

Specifically expressed in kidney and to a lower extent in liver, lung, spleen, brain, skeletal muscle and heart. In kidney, expressed in proximal tubules at the corticomedullary junction. Isoform 2 is specifically expressed in kidney. Isoform 1 is expressed in kidney and pancreas while isoform 3 is specifically expressed in brain (at protein level). In brain, isoform 1 is expressed in astrocytes while isoform 3 is expressed in neurons (at protein level). In the eye, isoform 1 is expressed in cornea, conjunctiva, lens epithelium, ciliary bodies and retina while isoform 2 is detected only in the conjunctiva.7 Publications

Developmental stagei

Expression is first detected at E17 in spinal cord and starts in forebrain at birth. Higher expression in brain is detected at postnatal day 15 and persists throughout adulthood.1 Publication

Inductioni

Down-regulated after cadmium-intoxication and sodium or bicarbonate loading (at protein level). Down-regulated by HCO3[-] loading.3 Publications

Interactioni

Subunit structurei

Interacts with CA2/carbonic anhydrase 2 and CA4/carbonic anhydrase 4 which may regulate transporter activity. Isoform 1 but not isoform 2 interacts with AHCYL1 (via PEST domain when phosphorylated); the interaction increases SLC4A4 isoform 1 activity. Interacts with AHCYL2.By similarity

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
