CC -!- FUNCTION: May be an autocrine factor that promotes the growth of
CC fibroblasts and is involved in the neoplastic transformation of
CC fibroblasts by v-Src. Chemotactic for peripheral blood mononuclear
CC cells as well as for heterophils.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC -!- INDUCTION: By serum. Expressed constitutively in Rous sarcoma virus
CC (RSV) infected cells.
CC -!- SIMILARITY: Belongs to the intercrine alpha (chemokine CxC) family.
CC {ECO:0000305}.
