CC   -!- FUNCTION: Golgi serine/threonine protein kinase that phosphorylates
CC       secretory pathway proteins within Ser-x-Glu/pSer motifs and plays a key
CC       role in biomineralization of bones and teeth (PubMed:22900076,
CC       PubMed:22732358, PubMed:25789606). Constitutes the main protein kinase
CC       for extracellular proteins, generating the majority of the
CC       extracellular phosphoproteome (By similarity). Mainly phosphorylates
CC       proteins within the Ser-x-Glu/pSer motif, but also displays a broader
CC       substrate specificity (By similarity). Phosphorylates ERO1A, enhancing
CC       its activity which is required to maintain endoplasmic reticulum redox
CC       homeostasis and for oxidative protein folding (By similarity). During
CC       endoplasmic reticulum stress, phosphorylates P4HB/PDIA1 which induces a
CC       functional switch, causing P4HB to change from an oxidoreductase to a
CC       molecular chaperone (By similarity). This is critical to maintain ER
CC       proteostasis and reduce cell death under ER stress (By similarity).
CC       Phosphorylation of P4HB also promotes its interaction with ERN1,
CC       leading to reduced activity of ERN1, a key sensor for the endoplasmic
CC       reticulum unfolded protein response (By similarity). Required for
CC       osteoblast differentiation and mineralization (By similarity).
CC       Phosphorylates casein as well as a number of proteins involved in
CC       biomineralization such as AMELX, AMTN, ENAM and SPP1 (PubMed:25789606).
CC       In addition to its role in biomineralization, also plays a role in
CC       lipid homeostasis, wound healing and cell migration and adhesion (By
CC       similarity). {ECO:0000250|UniProtKB:Q8IXL6,

CC   -!- SUBUNIT: Homodimer; disulfide-linked (By similarity). Interacts with
CC       FAM20A; probably forming a heterotetramer of 2 subunits of FAM20A and 2
CC       subunits of FAM20C (PubMed:25789606). Interacts with COPII components
CC       SEC23A and SEC24A; transport of FAM20C from the endoplasmic reticulum
CC       to the Golgi is likely to be mediated by COPII vesicles (By
CC       similarity). {ECO:0000250|UniProtKB:Q8IXL6,

CC       Endoplasmic reticulum {ECO:0000250|UniProtKB:Q8IXL6}. Note=Resides in
CC       the Golgi apparatus membrane and is secreted following propeptide
CC       cleavage. Retained in the endoplasmic reticulum (ER) in response to ER
CC       stress where it phosphorylates P4HB. {ECO:0000250|UniProtKB:Q8IXL6}.
CC   -!- TISSUE SPECIFICITY: In the mammary gland, expressed at higher levels in
CC       lactating mice than in virgin mice (at protein level)
CC       (PubMed:29858230). Highly expressed in the tooth. No expression in the
CC       dental pulp. At the secretory stage of amelogenesis, it is detected in
CC       the matrix of the enamel, in the ameloblasts, and within the cells
CC       adjoining the stratum intermedium (a tissue layer analogous to the
CC       stellate reticulum seen in the developing molar). Strong expression is
CC       observed in maturation stage ameloblasts and throughout the non-
CC       cornified layers of the gingival epithelium. Expressed at moderate
CC       levels in bone and at low levels in kidney, liver, brain and lung. Very
CC       low expression, if any, in spleen and skeletal muscle.
CC       {ECO:0000269|PubMed:17369251, ECO:0000269|PubMed:21549343,
CC       ECO:0000269|PubMed:29858230}.
CC   -!- DEVELOPMENTAL STAGE: In the developing tooth, initial expression
CC       observed in odontoblasts at all stages of development. At later stages,
CC       restricted expression pattern in ameloblasts. Also observed in
CC       osteoblasts in the alveolar bone. {ECO:0000269|PubMed:17369251}.
CC   -!- PTM: N-glycosylation is required for folding.
CC       {ECO:0000250|UniProtKB:Q8IXL6}.
CC   -!- PTM: Autophosphorylated. {ECO:0000250|UniProtKB:Q8IXL6}.
CC   -!- PTM: Propeptide cleavage by MBTPS1/S1P promotes FAM20C secretion and
CC       maximal kinase activity which is essential for efficient osteoblast
CC       differentiation and biomineralization. {ECO:0000250|UniProtKB:Q8IXL6}.
CC   -!- DISRUPTION PHENOTYPE: Mice survive to adulthood and show
CC       biomineralization defects, suc as severe amelogenesis imperfecta (AI).
CC       In addition, mice are severely hypophosphatemic and develop notable
CC       lesions in both dentin and bone. {ECO:0000269|PubMed:22732358}.
CC   -!- SIMILARITY: Belongs to the FAM20 family. {ECO:0000305}.
