Chain A   (FST_RAT | P21674)
molecular function
    GO:0048185    activin binding    Interacting selectively and non-covalently with activin, a dimer of inhibin-beta subunits.
    GO:0043395    heparan sulfate proteoglycan binding    Interacting selectively and non-covalently with a heparan sulfate proteoglycan, any proteoglycan containing heparan sulfate as the glycosaminoglycan carbohydrate unit.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0002244    hematopoietic progenitor cell differentiation    The process in which precursor cell type acquires the specialized features of a hematopoietic progenitor cell, a class of cell types including myeloid progenitor cells and lymphoid progenitor cells.
    GO:0032926    negative regulation of activin receptor signaling pathway    Any process that stops, prevents, or reduces the frequency, rate or extent of the activity of any activin receptor signaling pathway.
    GO:0046882    negative regulation of follicle-stimulating hormone secretion    Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of follicle-stimulating hormone.
    GO:0000122    negative regulation of transcription from RNA polymerase II promoter    Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0051798    positive regulation of hair follicle development    Any process that activates or increases the frequency, rate or extent of hair follicle development.
cellular component
    GO:0005575    cellular_component    The part of a cell, extracellular environment or virus in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together.
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
