Members of the cytochrome b561 (CYB561; MIM 600019) family, including FRRS1, reduce ferric to ferrous iron before its transport from the endosome to the cytoplasm (Vargas et al., 2003 [PubMed 14499595]).[supplied by OMIM, Mar 2008]
Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including establishment of mitotic spindle orientation; neuron differentiation involved in amphid sensory organ development; and regulation of cell differentiation. Located in nucleus. Expressed in several structures, including AB lineage cell; AWC-ON; M.dla; head; and somatic nervous system. Human ortholog(s) of this gene implicated in oculoauricular syndrome. Is an ortholog of human HMX1 (H6 family homeobox 1).
Predicted to enable monoatomic cation channel activity. Involved in defecation. Predicted to be located in plasma membrane. Human ortholog(s) of this gene implicated in amyotrophic lateral sclerosis-parkinsonism/dementia complex 1; cataract; and congenital stationary night blindness 1C. Is an ortholog of human TRPM1 (transient receptor potential cation channel subfamily M member 1); TRPM3 (transient receptor potential cation channel subfamily M member 3); and TRPM7 (transient receptor potential cation channel subfamily M member 7).
Enables phosphatase binding activity and protein-macromolecule adaptor activity. Involved in positive regulation of sarcomere organization. Located in M band and striated muscle dense body. Expressed in body wall musculature.
Predicted to enable protein tyrosine phosphatase activity. Predicted to be involved in G2/M transition of mitotic cell cycle; positive regulation of G2/M transition of mitotic cell cycle; and positive regulation of G2/MI transition of meiotic cell cycle. Predicted to be located in cytoplasm and nucleus. Expressed in several structures, including ganglia; germ line; male-specific anatomical entity; pharyngeal cell; and ventral nerve cord.
Enables cytoskeletal protein binding activity. Involved in several processes, including locomotory behavior; myofibril assembly; and post-embryonic body morphogenesis. Located in M band and nucleus. Expressed in anal depressor muscle; body wall musculature; head muscle; and vulval muscle.
Predicted to be involved in rRNA processing. Predicted to be located in nucleolus. Predicted to be part of Mpp10 complex and small-subunit processome. Is an ortholog of human MPHOSPH10 (M-phase phosphoprotein 10).
