COMMENT     REVIEWED REFSEQ: This record has been curated by NCBI staff. The
            reference sequence was derived from BU935536.1 and BP209293.1.
            
            Summary: The protein encoded by this gene is a member of the S100
            family of proteins containing 2 EF-hand calcium-binding motifs.
            S100 proteins are localized in the cytoplasm and/or nucleus of a
            wide range of cells, and involved in the regulation of a number of
            cellular processes such as cell cycle progression and
            differentiation. S100 genes include at least 13 members which are
            located as a cluster on chromosome 1q21. This protein may function
            in the inhibition of casein kinase and as a cytokine. Altered
            expression of this protein is associated with the disease cystic
            fibrosis. Multiple transcript variants encoding different isoforms
            have been found for this gene. [provided by RefSeq, Jan 2016].
            
            Transcript Variant: This variant (1) represents the longest
            transcript and encodes the longest isoform (a).
